John's place was very cozy and perfect for a stay of a couple of nights. Communication was quick and easy, and he was very kind and accommodating when I asked to add a second guest to the reservation. The house was about a fifteen or twenty-minute walk from Porter Square in a very nice neighborhood, and the self check-in was very easy. It was a pleasure to stay in an apartment where someone actually lives, rather than the sterile Airbnb hotel situation that is common in Cambridge and Somerville. The room was small but perfect, with a very comfortable bed, and the bathroom had terrific water pressure in the shower. Best of all, the place is warm and quiet.
