Was my first stay with airbnb and it was great! I met Todd at my arrival and he is a very nice host. BThe room was very clean and the bed was comfortable. You can access it by an extra entrance and with a door code. You share the bathroom with another guest, but it worked fine. I never saw the other guest. If you arrive with a car you can for sure find a parking place in the street right in front of the house. Harvard university is a nice walk about 15-20min. You can get to Boston downtown by bus or train. I can definitely recommend it!
