What guests think

AC Hotel by Marriott Portsmouth Downtown/Waterfront draws strong praise for its clean, modern rooms, welcoming staff, and a highly rated rooftop bar/restaurant, alongside a walkable location near downtown dining, shops, and the waterfront.

Guests find rooms spacious and comfortable, though some cite dim lighting, slippery showers, limited storage, HVAC quirks, and occasional noise or views that face construction or service areas. Recurring complaints focus on paid valet parking and a daily destination fee, with additional service hiccups like missed wake-up calls, billing errors, or inconsistent housekeeping. Expect a contemporary, central stay with lively social spaces, but budget for extra fees and consider room placement.

Great location with reliable Marriot quality. As a Bonvoy member, not thrilled with the $25 Destination charge on arrival, which we did not use.

I was told that if we spent money at the property, ie.. restaurant and bar, our destination fee would be refunded. That was not the case. $25 per day per room plus $1.63 taxes on that fee!! We spent $126.00 the first day at the rooftop restaurant and they would only reimburse $25 for one room and I had paid for 2rooms. And you have to spend $25 dollars, specifically assigned to each room each day?!? Which was not clear in their policy.

Very close to the main shopping area. Valet parking is $40 per day. But we used a nearby parking lot for $20 a day. 5 minutes walk to hotel. Rooms are quite new and clean. Lighting design is modern/fancy in the guest rooms, but not adequate lighting in my opinion.

Nice smart feeling hotel, comfortable bed, free coffee every morning in the foyer. Unfortunately room service kept ‘forgetting’ to service our room. Reception apologised for this but still did not fix the issue so rubbish accumulating in the bin and no fresh towels or toilet rolls during our stay etc. disappointed as a result which was a shame because everything else was fine

We enjoyed the comfortable room and the well darkened shades. The bathroom was nice…could have used a little extra clean but in good shape. Our issue was…we were in room 252. And right outside that zone of rooms is a workspace, van/truck drop off, recycling, trash, etc. SO starting at 6:30. Hotel Doors slamming, car/van/truck doors slamming. Bins being thrown into the trash and recycling. Compactors and other machines running. So not very restful. Unless you like being up with the birds on vacation.

Very modern and clean Attentive and helpful staff Delicious breakfast (at cost, but includes buffet and special menu) The reason for my rating is simple. The AC is set to ultra ECO mode and shuts off when you sleep. I don't know about you, but I can't sleep if it's 77 in the room. I won't stay there again.

This was a beautiful hotel with a fun rooftop dining experience! Things to consider before you book though: parking is $40 a day and there is a $25 mandatory spend charge each day on top of the standard room rate and taxes. The staff were friendly and location was great. I just wish those extra fees were in the standard rate to begin with. It became a very expensive stay quickly.

Parking was great but expensive. Worth the price for the convenience. Just wish it was a little cheaper. Lost 1out of 3 nights sleep due to guests in next room partying. Finally placed call to front desk and someone did come up but by the time they all settled down we were wide awake and too agitated to sleep. $18 breakfast in the kitchen??? We went in, got a table, and checked out what was left of the buffet. Most dishes were empty. The quiches were cold, no oatmeal, one croissant that 3 people wanted, no plates. We literally were so looking forward to this but ended up leaving.
