We had a lovely stay with John. He gave us a nice walking tour of the neighborhood, took us to get some Charlie cards, informed us which buses to take, fed us breakfast. He's very easy-going and accommodating.

Do note if you are visiting during the summertime that the room is not air-conditioned. We weren't aware that early July in Cambridge could get so hot -- now we know! There is a ceiling fan. If you are very sensitive to the heat, this would not be the best place for you.
