This place was a great stay close to downtown Boston and very central to surrounding areas with easy access to both the major highways and the airport. The T (subway) is also close but I would say a bit more than a walk if you want to use it frequently. We had 12 adult men who didn't feel like sharing beds so we had to bring three air mattresses and bedding to make it work. The hosts where very accommodating and they added a new bed knowing we where coming so that was fantastic.
The hot tub was the jewel of the stay. While we where there we had two frigid nights so the hot tub was a lot of fun and incredibly relaxing. My only concern was that the space while technically private, is sandwiched between other buildings. I was worried about being too loud with a bunch of guys outside late night.
I would recommend this space to anyone with a larger group. Having 7 actual beds (and a large couch) plus 2.5 baths was great.
