Posh and perfect location
We stayed here for one night the night before flying home out of Logan. Our room looked down onto the Boston Public Library, Copley Square, and Trinity Church. One block off of Newbury Street with tons of shops and restaurants. The T stop is one block away. We took advantage of the proximity to the T to return our rental car a day early and see the city and go to the airport the next day all on public transportation. I always recommend ridding yourself of a car as quickly as possible after entering Boston. 
We received exceptional service from every single member of the staff, but still with a taste of Boston wit rather than the obnoxious, obsequious service you can get at some other hotels. Restaurant and travel recommendations were swift and spot on, and they held our car for us out on the street while we checked in and dropped off our bags. Not an easy feat on Boston streets. 
The room was beautiful and luxe. We were on the 11th floor, in a hypoallergenic room, though we did not specifically request one. We slept great and had a perfect base for all of our site seeing. We didn't eat in any of the restaurants because I simply had to have a Dunkin Donuts pumpkin muffin one last time before leaving.
