John's apartment seems to be a great bargain for this area, where Airbnb's seem to be relatively expensive. My experience was satisfactory. The apartment was in a good location in Cambridge. Checking in was a slight hassle. After I booked a room (ie paid for it) I had to go back and forth with John before getting the front door code, which seemed atypical. I stood outside the house for 15-20 minutes in February waiting for him to send me the door code. The apartment itself was clean enough, though I felt the room could have been made a bit cozier with not a ton of extra effort. The bathroom could have been a bit cleaner too. My room was next to the kitchen and people were hanging out in there quite late at night. Not John's fault, just something to consider if you're looking for a quieter stay.
