The location is fantastic, central to the aquarium, Faniel Hall and a 15 minute walk to the North End and Boston Commons. We stayed here with a 6 year old, almost 4-year old and a 4-month old and we were able to do most of the city without needing a car (walking and stroller).
The home was clean, my kids loved the bunk beds and the neighborhood was quiet at night. There is an elevator, which made moving in and out a breeze and the street parking was pretty readily available for doing so. We used a valet garage service for the car during our trip that was literally 2 blocks down the street. Local food options for a fast-meal were excellent.
Highly recommended.
