We stayed for one night. The apartment has 4 good sized bedrooms and 2 baths. The beds were nice and comfortable for the four of us. Note that the windows in the bedroom open into a central space - so you may have to have the blinds drawn for privacy. The kitchen is convenient with a nice range and appropriate plates and dishes. The shower was nice and hot which was perfect after a day of walking around. The park street T stop is minutes away by walk. You don’t need a car really.
We came by car because we came in from out of town. Note that there is no parking - we parked in a nearby lot which can get expensive for longer stays.
