Very comfortable room in a super clean home, just as described. The closest is huge--a walk-in--which was very helpful for organizing things. Hosts were all friendly and because this is their home, it felt more secure than the other room-only places I've stayed. The air conditioner kept the room pleasantly cool even on hot summer days.
One suggestion to guests: leave the bathroom door open when it's not in use! otherwise it's hard to tell if someone is inside.
I loved the location, which for me was about an 8-minute walk to Davis Square (subway station). It's almost as close to Porter Square and Alewife stations, and there are frequent busses around the corner.
