Old hotel and looks it.
I stayed here for the Boston Marathon. The location is ideal. What you gain in location you lose in hotel amenities. Rooms do not have refrigerators or mini-bars. The rooms are small in nature. The furniture has seen many guests. One unique feature of the hotel, the hallways seem wide enough for driving a car. The lobby, while grand seemed dark to me. There is a mobile coffee kiosk based in the lobby during the morning. The kiosk does not add any charm to the lobby.
 If you have the urge to experience what it was like to stay in a hotel in 1930's this is the hotel to stay at. 
On the positive side, the staff seemed genuinely concerned about guest needs.The hotel is also surrounded by many restaurants. I would suggest the Au bon pain for breakfast.
