Location, location, location indeed. A terrific central location, right on the Freedom Trail, and close enough to everything. Most of Boston is very walkable from the apartment, with ready access to a lot of history. The elevator to the floor was appreciated on checkin/out but we used the stairs for the middle of the stay.
The apartment itself is very nice and well-furnished. We were originally a little worried about the proximity to the theatre, but did not hear anything when a large'ish show let out - nice sound insulation. Plenty of pots and pans for cooking in, but frankly, we ate out every meal and only used the coffee maker.
Both bedrooms were roomy and the beds were comfortable. The hosts were very responsive to a couple of questions we had. Bathroom was nice and serviceable. Couches and other furnishings were likewise comfortable. The furnace was responsive, as was the wifi.
