What guests think

At Courtyard by Marriott Houston NASA Clear Lake, travelers consistently praise the convenient, safe location near Space Center Houston and the friendly staff, while feedback on room comfort, housekeeping consistency, and on-site food value and availability is more mixed.

Many guests find rooms quiet and comfortable, though several mention very firm beds and flat pillows, occasional maintenance issues, and some dated elements. Cleanliness reviews range from spotless stays to reports of missed housekeeping and occasional issues like dirty bathrooms, leftover fridge items, or pests. The bistro and breakfast draw frequent comments: no complimentary breakfast, limited selection at times, and prices that feel high, though some meals and Starbucks drinks are enjoyed.

Overall, it was okay. Great location if you are visiting Space Center. Nice to have washer/dryer on-site. Big con…the keycards would demagnetize every time we used them. Had to get new ones 3 times in 2 days!

Nicest and most helpful staff I’ve seen in a while. Only issue I had was no towels in the swim area but told the front desk and they delivered to us personally. Will be back.

I would have given 5 stars to everything, but the hotel ran out of hot water (apparently repairs were imminent) so I had a cold, cold shower. I like the design and decor! Efficient, well laid-out rooms, simple and tasteful furnishings (none of those awful multi-colored carpets in common areas! Yay!). Other than cold water, it was a very pleasant stay.

Evening staff was unpleasant. Door lock was broken. Staff made us go up and down 3 times before sending someone to help. Front desk unfriendly. Stated that we don’t know how to use the lock on the door. Showers dirty. Windows and drapes dirty. No coffee or tea offered for guests. Very unfriendly place. Don’t recommend this place.

Stayed overnight for a visit to the Space Centre the following day. There was plenty of parking on arrival and a smooth and speedy check in. The room was spotless and the bed was comfy. Not a huge selection on the menu for dinner, but what we had was tasty. Likewise, the breakfast was good too. Overall a really great stay and a perfect location for the Space Centre. Would highly recommend.

The room wasn't very clean. Food crumbs were on the couch, the bathroom floor had hair and make-up, and the sink didn't drain well. But the staff were fantastic -- very helpful and professional. If the rooms were just cleaned and maintained better, it would be the perfect place to stay.

Hair is hanging on the walls in the shower and again we asked for some more pillows because of the crêpes that were in the room told the man two times at the front desk. He assured us they would be sent up never were. We had the worst nights sleep ever at any hotel will never recommend and will never stay at another one of your hotels, horrible service and filthy room and horrible bedding.

The hotel is clean and the staff was friendly, great lobby with seating area for the coffee, food and drink bar and an open lounge area. Walkable to Space Center but we chose to drive. Room was nice with all the necessities, I would love to give 5stars all around but the mattress and pillows were dreadful.

Didn’t have bedding for the pullout, there were ants all in my room, the room above me must have been hosting the circus because there was running and so much noise, then I had to put up with the elevators next door and everyone that was loud in the hallway. I was added to the cleaning list for the next day and they never came or refreshed my towels. The only positive was that there weren’t any bedbugs. I won’t stay here again, unfortunately.

Our stay began with a difficult check in , waiting several minutes while the check in clerk kept going back to an office to check on something. We had requested a room at the back of hotel, which we did not get- and the clerk asked us to wait while she went up to "check on a room to see if it was clean". Not a great initial impression. We followed her up because we were in a time crunch for a dinner, and the room did not have feather free pillows as we requested. She also flushed the toilet, which obviously led us to believe the room had not been prepared for us ahead of time. Upon our check out and leaving a bag in the room, our subsequent phone call from the hotel was quite strange. We had told them that we had a hassle checking in to the hotel and the clerk accused us of calling her an "a-hole". I dont think she knew the meaning of the word hassle. Regardless, we will not be staying here again and hope they give their clerks better front desk training.

We at at the bistro downstairs for breakfast one morning and for 4 people, we paid $90 for a very basic meal. Also, we stayed 2 days. We expected our room to be cleaned / serviced while we were out the second day and were disappointed to find that our room was not serviced. No clean towels, our garbage was still there, and our beds were not prepared. Not the end of the world. But if you charge like a higher priced hotel, we should get the amenities of a higher priced hotel.
