We coordinated this weekend to participate in a Girls Volleyball Tournament. We were three moms traveling with our teen daughters. The hosts were very detailed in the information provided, responded quickly to any inquiries, and went way above and beyond when asked for recommendations for local attractions and food. The "unit" is easy to find, very clean, and well equipped. We drove to Boston, but used the subway to travel; it's a 30 second walk. The stairs inside the unit are tight, but manageable. If water pressure and/or mattress comfort matter to you... you will not be disappointed. They also don't have a long list of "chores" to be done before leaving. Five stars, and they earned them all!
There's not a garage or assigned parking, so it was a challenge. (not a dig on the hosts or the unit, just a planning point)
I would absolutely stay again, the location is everything, and the hosts were amazing!
