The Chicago Hotel Collection Millennium Park

Valet service was underwhelming, they were either not around or off the clock often and they ended up parking my car on the street outside overnight for our 7AM departure. For $100 extra a night, the valet was really not worth it. I recommend staying here if you do not bring a car. The rooms are clean and spacious, the carpets and furnishings are modern and have recently been replaced in some areas. The hallways are a bit loud but otherwise the rooms were quiet. We were upgraded to a larger suite, but it was still quite small (to be expected downtown).

Great location, but just off Miracle Mile. Great art. Wonderful room layout. Best gym at a hotel I can remember. Helpful staff. Finally ate breakfast at Lure the last day and it was great - and you get a 21 percent discount there if you're a hotel guest. This was family vacation and our 20 and 18 year old had their own room on the same floor and that couldn't have worked out better.

Hotel in great location and room was perfect. Only negative, one of the two elevators was out most of the stay which caused delays.

Hotel was extremely clean and well kept. Front desk staff at check in were great. The restaurant had fabulous food, but I didn’t get the 15 percent discount I was told I would get as a guest. The room was very clean. The water pressure is awesome. I’ve stayed when it was 21C and enjoyed my stay as Hotel 55. Bonus that Trader Joe’s is across the street and Eataly just a block away.

Great customer service- always and the food at the hotel restaurant was amazing!

I think this is a refurbished hotel. The front is clean. They have unique art in the foyer and an upstairs gallery. There are two elevators….seem pretty fast and we don’t wait. The floor we were on was a bit tired. Our room was quite nice. Very hot shower. Nice lighting. Bed is medium firmness which was a snitch soft for my wife (but how do you know!?!). Fitness centre has a lot of equipment for the space. Nice mix of treadmills, bikes, and strength. The surrounding area has nice shops and nice restaurants nearby. There is a fair amount of street noise at night (sirens from ambulances). For the price point quite reasonable.

The hotel and staff was wonderful. Lack of/expensive parking wasn't communicated well.

Well run property; great gym; friendly staff

Nice art focused hotel near Michigan avenue though it feels a bit worn. Breakfast menu at LURE very meager and costly for the place. Very small elevators and slow to get to rooms. Limited small work out space in basement kind of gloomy. It feels less like a 21c brand hotel than others

Elevators gave us constant trouble. Room cards would not work. Stressful and unnecessary

Arrived to poorly lit halls leading to room. Very unpleasant smell in room. Dirty tabletops in room, trash under furniture, walls with dings & chipped paint, the “closet” was an old makeshift cabinet, robes looked like they were from GoodWill, previous guests dirty underwear in bathroom! Disgusting!!!

The check in process was easy. Room and bathroom were clean.

Every was almost perfect…loved the art display, staff was great, rooms very nice and clean, but they should clean elevators more. If it comes up we will recommend and stay again.

We had a wonderful stay at the 21c museum hotel! I wish it was for longer than one night. Clean, convenient to everything, comfy bed (very important), nice, hot shower with good water pressure (important) and friendly, kind staff. Highly recommend for anyone staying in Chicago!!

Hotel is centrally located and convenient, don’t believe our room was fully cleaned though, found an old food container on the ground.

The bathroom was dirty (toilet seat was visibly not cleaned) and the carpet was stained. The beds were very firm and uncomfortable-overall the location is good but the hotel is not clean and could really use some attention.

Staffing was very nice and helpful. Clean rooms, excellent amenities and beautiful location.

Very clean hotel, friendly staff. Loved the decor and art exhibits. Very convenient to Rush St and Michigan Ave shops and restaurants. Comfortable beds and pillows, got three great nights of sleep. The 21C Museum Hotel does not have the awful motion sensor thermostats that many of the larger chains (Marriott) are now using. This allows the guest to continuously run the HVAC fan and have good white noise while sleeping. I would definitely stay at the 21C again, and will look to stay at their locations in other cities. Thank you 21C for a great stay.

The location in very good but the property while appears clean had mildew in the bathroom probably because the room I got was dark. Now the price is low so, it’s up to you….

Pros: Overall is good. The room is clean and quiet. Noise isolation is so well. My baby didn't bother others when she was crying and we didn't hear any noise in the room during the stay. Staffs are nice and helpful. The location is surrounded by a lot of decent restaurants. 1 minute walk to the Michigan Ave which is like the 5th Ave in the New York City. Cons: No bedside light control. 1 bed reading light is not working. No air ventilation in the bathroom. The bathroom will be full of steam when you take a shower. The coffee machine is in the cabinet is a little awkward. You will need to pull out the machine to refill water after you pull all the way out of the drawer and the power cord is holding it back. TV can only watch TV program even it's a smart TV. Unable to watch youtube, netflix, etc.

The place is loud!!!!!!!!!! We had a room literally facing a Main Street, and we heard sirens, loud music from cars, and people yelling until 4 am. The staff are incredible, and it’s a fantastic hotel. They need to invest in sound proof windows

Nice hotel, starting to show some wear and tear. Showers are incredible.

Very nice stay. Strong shower head. Nice water bottles.

Really nice location and huge room

Nice recent renovated hotel, building is old but has good shower water pressure. However, the ac is tooooo loud.

Staff and location—high marks. Our room was “quirky”—a mirror in the shower; only found one outlet that was useable. Phone and clock between the beds were not plugged in and the outlets were behind a built-in headboard that we could not see or get to.Not sure how to explain……TV was set to Spanish so we couldn’t read instructions. If we did find a station in English, the tv would randomly switch to Spanish. Mostly, the tv stuff made us laugh, but the lack of working outlets was frustrating. Bed was comfortable. Again, thanks to the staff who made our check-in and check-out very pleasant.

It's clear this hotel was in the process of changing hands when we stayed there. There were issues with the in-room TV and phone and limited outlets (and none next to the beds). The air filter appeared visibly dirty in both the bathroom and bedroom. The rooms were much smaller than appeared online. We stayed on the 4th floor and the street noise was very loud. Heard from a friend on the 11th floor that it was also loud up there, so may be unavoidable. I hope the new owners clean things up a bit! Otherwise, the staff were very nice and friendly.

Great hotel for tourists but not ideal for business travelers. No desk in room and no outlets by the bed! The weirdest thing I’ve ever seen. I had to plug my phone in across the room and hope I woke up to my alarm. Large, comfortable room but would love some outlets!

21C is a smaller hotel two blocks from Michigan Ave., so it was very quiet in our room but easily walkable to anything. Upgraded to a very large room with king bed and 2 sitting areas — very spacious! Clean all around, easy self-parking nearby although we used valet. Lobby is filled with cool art installations which we enjoyed. Would definitely stay again.

I have stayed here before and I love the location and the art vibe. This visit, the room was fine at first but it became apparent that the AC wasn't working. We called the front desk and they sent someone up to fix it and unfortunately he broke the system causing us to move to another room. No big deal. The security man came up and helped us move all our stuff and gave us the key to the new room while he took the larger service elevator. We arrived there first and were dismayed to see a dirty paper towel on the floor. Upon further inspection it seemed that the only way to turn on the light in the bathroom was to go into the dark bathroom and close the door completely because the light switch was actually behind the door. We then asked to be moved to another room and the security guard came up and helped us move again. The thing we found distressing was the attitude of the people on the front desk as if not having AC and seeing someone's dirty towel was acceptable. They finally agreed to make a minimal adjustment to the bill. This is not a cheap hotel and the laissez faire attitude of the staff really put us off. I would not have expected any compensation had the staff expressed any genuine concern for the situation. The staff who cleaned the room we ended up in were very pleasant and did a good job. Having said all this, the hotel is in a great location and the art work is wonderful. I don't think I would stay there again but I would certainly visit if only to see the art.

The hotel was acquired by Marriott after I made the reservation through Hotels.com. Although they sent email saying they would honor the reservation when we arrived at 6:00 PM they had difficulty finding a reservation and did not have a room ready. They did not offer the same price as reserved blaming everything on the systems not being integrated as of yet. We were eventually offered an upgrade.

I typically book exclusively with Hilton. After our brief stay, I remember why. This hotel is aesthetically pleasing and in a nice location downtown Chicago. The room was small, but quaint with a modern flare. However, all was overshadowed by extremely poor service at the front desk. Arriving early, we were not greeted by the check-in staff. While stowing our bags for a couple hours, the same woman failed to tag them, luckily noticed by a coworker. My second trip to the front desk was equally disappointing. Once again, I stood awkwardly without being greeted, by a different employee. And finally, there was a delay retrieving my vehicle from valet, due to failed communication between staff. Definitely over-priced for the quality of the service.

Staff was excellent. Able to get me in my room early and upgraded it. Parking was quick and easy. Everything is within walking distance. Room was clean and well kept.

The front desk staff was exceptionally friendly and helpful, especially Francisco. The property was immaculate. It was a great location for walking everywhere. We never had to wait long for an elevator. The room was a good size, the beds were very comfortable and we even had pillow options, i.e. soft and hard pillows. I would highly recommend this hotel

We have stayed at other 21C properties and had exceptional service and experiences, until this time. We seemed to have been an interruption to the front desk staff at check in instead of welcomed guests. After reaching our room with a nonfunctional refrigerator and not stocked mini-bar, we were informed it was due COVID from a few years ago. The last straw was when we entered the attached restaurant, that is independent from the hotel’s ownership, and the staff here asked for our drink and food discounts from the hotel. We never received these vouchers at check in. When asking the front desk at 21C about this, we were again met with sighs and eye rolls as they slapped out our vouchers and abruptly turn away. Never did we hear any staff member offer assistance or apologies for any of these incidents. We have even tried to reach a manager through their website to hopefully allow them to understand and be aware of these behaviors, but have not had any responses.

Great hotel with friendly staff

they cancelled my room and had no rooms available. Everything was booked downtown and they had no accommodations.

Staff is very understanding and Welcoming

The staff was extremely friendly, the room was clean, bathroom was so nice, great location also!

We had a great stay at the 21c Museum Hotel. The location is amazing—just one block off the Magnificent Mile, with Trader Joe’s and Marshall’s right across the street, and only two blocks from the Starbucks Reserve. Super convenient to multiple bus lines and the red subway line, all within a short walk. Our room was clean and comfortable, with everything we needed. We didn’t get a chance to try the restaurant or the gym. No complaints at all—would happily stay here again!

Great location

Great location, close to dining, shopping and attractions.

Perfect central location location for an exploration of Chicago. My wife and I were able to get everywhere via the CTA including O'Hare. Very cool and thought provoking pieces of art.

Perfect location - close to Michigan Ave and to many public transit options.

Great location.

Great hotel in the middle of everything a tourist want to see/visit in Chicago.

Lovely hotel! Great location!

Room was clean bed was comfortable! The location was perfect, walking distance from restaurants, shopping and local focal points.

Good hotel. Didn't visit the museum but it looked nice. There was a restaurant but the online hours said there was no breakfast on Sunday, but the hours posted on the door said there was? Very confusing, I wish they had a better breakfast.

I really enjoyed staying here. It was clean and well maintained with helpful staff. The gym looked great but I didn’t pack my workout gear. The connected Lure restaurant was excellent to experience. River North is a wonderful location and a very short walk to great shops and restaurants.

It’s clean inside with basic decor in the rooms. The art exhibits are nice though. The Lure restaurant is not great so don’t waste your money there.

We loved the Offspring Exhibit, our room was nice, housekeeping was on point, breakfast was delicious

Interesting concept, a hotel built to include a modern art exhibit. While not fans of the genre, we were curious to see how the hotel integrated the museum component. Really liked the execution and enjoyed our king room. Bed and room furnishings were comfortable, and we appreciated the large-screen tv with easy access to the HDMI connections so we could hook up out computer for viewing and work. Unfortunately, the seating area is very small, so we had to coordinate movements when one of us wanted to get up and out of the space, but we made it work. The bathroom has ample room but for some reason they stuck the toilet next to the shower (as in just a few inches apart) which limits the space in front of the shower door. Why they did this when there is a good 4 ft between the toilet and counter is anybody's guess. Plenty of towels and two bathrobes made for a nice spa feel to the space. We also appreciated the reusable water bottles that came with the room as well as the coffee setup that included liquid creamer instead of the nasty powdered stuff most places use. The on-site restaurant is excellent and we highly recommend their selections. All the staff we encountered were lovely, personable and professional, Our only complaint -- the cost of valet parking ($75/24 hrs) is astronomical! Still, it was really nice not to have to worry about finding a parking garage nearby. We had a lovely stay and will probably stay here again.

We had a wonderful experience at this property. The room was spacious and clean, the restaurant downstairs was great, and the staff was friendly and helpful.

Nice art focused hotel near Michigan avenue though it feels a bit worn. Breakfast menu at LURE very meager and costly for the place. Very small elevators and slow to get to rooms. Limited small work out space in basement kind of gloomy. It feels less like a 21c brand hotel than others
