If you are planning to spend in Boston, I strongly suggest Dough's place. The location is walking distance from the central points of interests, and few mins from closest subway station.
The householder is available for any info with quick response, and it's very simple to access to the place.
The apartment is very cosy and I consider it part of my Bostonian experience; it's equipped with not one but two sound systems, and there's a beautiful view on Charles river if you'd like to drink a glass of wine on the balcony. Main room is very comfortable, the second bed is smaller but still ok.
