My family of four stayed in Gerard and Marie's place for five nights. It was a very clean and comfortable apartment. There was plenty of room for the four of us with my husband and I sleeping in the bedroom, one of our teenaged children sleeping on the pullout couch and the other sleeping on the blowup mattress. Gerard and Marie were easy to contact, and although they live right upstairs, we never heard them. It was very private. There's even a small private patio in the back. We enjoyed the peace and quiet of staying in Charlestown (as opposed to Boston proper); however, be aware that you do have to walk a bit to get to restaurants and the subway. Our favorite restaurant in Charlestown was Figs - about a 10 minute walk from the apartment - which has amazing pizza.
