"Other hotels are better and watch for an added $25 a day fee"
TripAdvisor user rating 3.0 out of 5
Reviewed February 13, 2026 NEW
1 Br Suite was kind of like a prison cell. Very dark and it was very difficult to get the temp right. The thermostat was way up by the front and the bedroom was a full 10 degrees different in the back. So, one room cold and the other hot. You needed to be an engineer to get the lights to work, one central switch by the front door to save on electricity like in Europe but there was one light in the bedroom that could not be turned off by any switch in the whole room. Lastly, they steal $25 a day (destination/visitor fee) and give you it as a credit. Only if you eat breakfast, use the bar or buy tons of unhealthy snacks do you get the money back. I don't do any of those things so used about $25 on bottled water through the week and lost $100. Basically, do not stay here... there are lots of other hotels that are better and don't sneak fees in to rip you off.

"Beware destination fee add-on"
TripAdvisor user rating 2.0 out of 5
Reviewed January 24, 2026
Hotel was fine However they added a destination charge at check-out which was not disclosed either at the time of booking or during check-in. Their confirmation email mentioned a $60/day valet charge, but not the destination fee. It took me several emails to get it refunded.

"noisy"
TripAdvisor user rating 3.0 out of 5
Reviewed January 21, 2026
light sleeper so take this with a grain of salt, but the windows, doors, and floors are pretty thin and don't do much to block out any external sound, so it doesn't really matter where you are in this hotel, you're going to hear *something.* the freeway side is clearly the worst - they're thoughtful enough to provide earplugs and a noise machine but your single-pane window is 50' from the last remaining elevated piece of the central artery: you're going to hear it. the other side is much better but beware of the whole foods loading dock on north side of the building if truck backup beepers can wake you up, the middle of the building if elevator dings can do the same, and anything but the 6th/top floor if you want to avoid noise from people walking on the hollow wooden floor above you. the staff are really nice and do what they can but it's pretty obvious the hotel was built on the cheap and there's not a lot they can do.

"AC HOTEL BOSTON DOWNTOWN and STAFF."
TripAdvisor user rating 5.0 out of 5
Reviewed January 21, 2026
The property itself was beautiful—clean, comfortable, and thoughtfully maintained—but what truly made the experience exceptional were the people. Jeffrey and Elizabeth A. Beutel deserve special recognition for their professionalism, warmth, and genuine hospitality. They were attentive, friendly, and consistently went out of their way to ensure everything was perfect. Whether it was offering helpful suggestions, checking in to make sure I had everything I needed, or simply greeting me with a smile, their kindness made a lasting impression. It’s rare to find a team that blends efficiency with such heartfelt service, and this hotel truly sets the standard. I highly recommend staying here—you’ll be treated not just as a guest, but as a valued friend. Five stars all the way!
