Our host Jonathan contacted us prior to our arrival and sent us detailed instructions on how to get into the flat, and where to find everything we might need. He also checked that we arrived safely and that everything was to our satisfaction. The flat is very clean, spacious, and in an excellent location. There is no parking, but we were able to find private parking close by, although the rates are not cheap. Public transportation is excellent in Boston, so a car is really not needed.
