Gabriel's apartment is by far the best air b n be we've stayed in! It was very clean, and had everything from dishwash soap to shampoo. It's great value for money in Cambridge/Boston, as parking is included and it has AC! It's a short walk from Porter square and about a 25 min walk to Harvard Square-great location. Based on other reviews I was a bit worried about the noise from the train, as I'm a light sleeper, but I slept really well.
