We had a great stay in Cambridge/Boston here. The flat is in a quiet Cambridge neighbourhood close to the Harvard business school and about 10 minutes walk from the 'Central' T stop on Massachusetts Ave. There's loads of bars, shops and restaurants up at Mass. Ave., so there's loads of good places to eat and drink within walking distance if you're not going into central Boston.
The flat itself is well proportioned, with a generous bedroom, small but well equipped kitchen, and a decent sized bathroom.
Daniel is a responsive host, proactive in making sure we found the place OK and knew how to check in, and equally quick to answer any queries we had.
