Nelson and Pauline were two of the nicest AirBnB hosts I've ever had! Their place is beautiful and a great base for exploring Cambridge, Somerville, and Boston. They greeted us on check-in to make sure we were all settled, and between the space, the welcome, and the little extra touches they prepared for us this place was definitely 5-star. If you're sensitive to sound you should know that there's a bit of road-noise because of location, but I still slept very well.
