We stayed with friends & families, kids ages 1-10. There were plenty bedrooms for everyone and it's difficult to find a place with so much space close to Boston. The property was in a quiet neighborhood with driveway parking that held our 4 vehicles, so 5-star location.
The bedrooms & bathrooms were top notch, and the beds themselves were comfortable.
The kids had plenty to keep them entertained - ample space and toys in the play room, an outdoor area that had a full playset and soccer goals, foosball table inside, etc. The house is not baby-proofed (e.g. the electrical outlets aren't covered, no child-proof latches on cabinets). There is some artwork in the house with nudity and sexual promiscuity.
Upon arrival we smelled gas. We called the property manager, who answered immediately, and explained that the smell could be due to the AC being run for the first time after a period of being idle. We aired out the house, which helped, but we went nose-blind to the smell and it seemed to come back each time the AC was turned on. Our fault for not calling the property manager back, as she did offer to send someone out to investigate if airing out the house didn't work.
We were locked out of the AC at midnight the day of departure, which made for a warm evening & morning. We saw a mouse outside day of arrival and inside as we left.
Refrigerator water & ice maker didn't work. Gas stove lit sporadically. Expired food in the cabinets. Kitchenware needed cleaning (e.g. tea pot).
