A friend and I stayed at David's place for Christmas. The location is awesome: ~10min straightforward walk to the nearest subway station, ~15min walk to MIT, ~40min walk to Harvard; the neighborhood is clean, quite and elegant. Rooms are spacious with a lovely design, everything is sparkling clean. The hosts are very detail-oriented and prepared a lot of little utility stuff in the bathroom and we absolutely love it. My personal favorite is the bluetooth speaker! We'd definitely stay for more days to fully enjoy the space if we had time.
