We were on the third floor of the house, in a lovely little room. We enjoyed our stay, which was walking distance (15 mins) from Harvard Square Station. The people in the house were friendly, and there are refrigerators and a fully stocked kitchen.
The one thing that surprised us was how dead Cambridge is at night. Friday night at 10 we were unable to find many open restaurants for food, which surprised us since we live in New York. Just be ready for that.
