Was expecting more...
Stayed here for 3 days. Front office staff was OK when we arrived but they offered the guest in front of us a room higher up as apparently were better and she stayed for 5 days. No mention to us at all, just the regular check in duties. 
Additionally I wouldn't exactly call this a boutique hotel. 
Rooms are on the small end and the bathroom was simply tiny. The sink was as small as an average toilet hand wash basin. Not sure if it was just in our room but for the price, I would have expected something slightly more.
Location is good, in the South End, easy to walk to Boston Common or hop on a bus.
