Room was ok, expected a bit more for the price. Just enough room for the bed, no claws closet. But ok overall. The most disappointing was that we had left for breakfast the day we were checking out, put all our stuff in the car and when we came back to the room to use the bathroom our room was being cleaned and we didn’t check out yet!

The handle on the night stand was broken. The phone did not work. I tried to call the desk with cell phone on multiple occasions, no one answered. The door have some sort of slow close which made me feel unsafe.

Everyone was very helpful, and the room was really very nice. This is a small hotel in a semi-industrial area, which may not be as appealing as a large hotel downtown, but it was a good place to stay while I was in Boston. I also agree that the reviews are mixed, but my room was very clean though, and the bed was comfortable and everything was well maintained. I realized that the negative reviews are all pretty old, so it looks like they may have done some major renovations lately. The recent reviews seem much better on all platforms. So I really had no complaints, other than the small desk (this was a business trip, and I had to do a lot of work in the room, including teleconferences). I looked at some other rooms while I was checking out, and it looks like other rooms had better desks. The internet was great though, even for online meetings. Compared to the big hotels downtown, I think this is OK, and definitely a better value. Belle's Burgers down the street (5 minute walk) was outstanding (really, you should try it), and I ended up eating there twice.

Clean and quiet. Only issues, bulbs were out in the bathroom so the one bulb that was working was dim. No shampoo. The bathroom door wouldn't shut, it had to be slammed to make it shut. The door to the room didn't latch unless you made sure you pulled it closed behind you a security issue if you didn't make sure it was locked before you left.
