Fine Rooms, Underwhelming Staff
Pros:
Rooms (suites) are spacious, comfortable, and well-appointed.
Excellent location close to the airport.
Very competitive rates for Boston.
Things to Consider:
Staff has some competence issues. 
Called the front desk to arrange a taxi twenty minutes before I needed to leave, but no taxi was called. Front desk then informed me that no taxis were stationed outside, (unlike most hotels,) because of some lingering dispute with the drivers, (lovely.) Cab was finally called, and arrived ten minutes later. Would have missed my flight if I had been cutting it close.
Conclusions:
The taxi issue is enough to make me think twice about booking in the future. You shouldn't have to wait for a cab at an airport hotel.
