Our group of 6 had a great stay at Katy's house. We didn't meet, but the contact has been easy, and Katy was very quick to answer our questions. She prepared the house, so that we felt immediately at home. The house, located in a nice residential area, is charming, definitely large enough to accomodate our group, and we also appreciated the garden. Boston downtown is reachable but bus+metro or by car. We recommend this place !
