My wife and I recently spent four nights at Maria's place. It's very comfortable; we needed both the A/C and heat during our stay, and both performed well. Very good appliances in the kitchen and a bright, comfortable living room. We slept well in the beautiful sleigh bed in the master bedroom. Note that the bathroom is on the first floor and the bedrooms are on the second, just something to be aware of.
The apartment is in a great location, just a few minutes from either the Forest Hills or Green Street stops on the Orange Line, which provided very convenient access to most of Boston's top destinations. Jamaica Plain is a delightful neighborhood, very walkable with great local shops and restaurants. Maria's place is an excellent home base for your trip to Boston!
