The space is a private attic area with bedroom and living room areas. The bathroom and kitchen are down a flight of stairs and shared. They are kept pretty clean. I did run into other occupants of the house on occasion; everyone was polite and the house is quiet.
All the amenities are updated. I especially appreciated the door codes built into the handles and all the dimmable lighting. The beds are comfortable and adjustable. The layout of things is very well thought out to be convenient, from placement of hooks to the platform for luggage in the closet.
The host is attentive, responding within minutes, and ready to help out right away.
Location is an easy 7 minute walk to the train station with a commuter rail to Boston.
