Very convenient location close to MIT and Central Square. Room was clean and comfortable. Based on previous reviews I knew the configuration of the apartments / rooms. Each apartment contains multiple private rooms and baths with a common space. There was another person staying in the same apartment, but I never saw him.
There is some street noise but it's a city and expected. Host was very nice and made me feel welcome.
This was my first experience with Airbnb and very positive. I would stay again if in the area.
The building is older and there are lots of stairs, so that might be a concern for some.
