The unit is one of several in renovated efficiency apartments. The building goes up to four floors with no elevator. The building is very clean, with hotel-like amenities in the room with a kitchenette. Everything was very comfortable and well-stocked, with exception of a hair dryer. However, there was a coffee-maker, so it evens out. ;-)
The location is the best part. Quick walk to the Convention Center, several T stations, tons of music schools, Northeastern, Opera and beyond.
I'd stay here again.
