Great service, beautiful hotel and lobby, rooms are just OK
The Liberty Hotel is a beautiful property and the restoration of the hotel (previously a city jail) is remarkable and worth the trip alone. From various parts of the hotel you can see the old brick, jail cells and remnants of the former building. It's an impressive place. The front desk staff and check-in process was efficient and very accommodating (a glass of grappa a welcome surprise too!). Room service was fast, the food was better than expected and though Boston's outrageous taxes can easily run up the fee, I feel it was worth it. 
So, the no-so-good part -- the room's cleanliness. I feel like every time I stay at a Starwood property, I get the same "so-so" approach to cleaning. The bathroom in my room was particularly average -- there was splatter on the wall by the toilet and sink, there were a few random hairs in the corners of the bathroom room and a few random splatters higher up on the mirror. In fairness, I didn't call the front desk to complain -- I was only there for one night and was generously upgraded to a room with an incredible view of the city so I overlooked those things. But, the room was loud due to the HVAC system and there is also very little soundproofing between the rooms. Not the best night's sleep... and the bed was just OK... very oddly lumpy. As a Marriott Gold member, I can see a clear difference between the two chains and for me, I'll stick with Marriott.
