On the positive side: the area and location were great. Free parking in a nice structure that was very close and easy was a great bonus. The unit was mostly as described and the hosts worked hard to make sure our stay was enjoyable and comfortable.
On the negative side: we found (and this was not exclusive to this place but seems to be a thing in most Boston AirBNB's) that they put more beds in than the space could handle in order to increase their occupancy. Its really a 2 bedroom place that would comfortably house 4-5 people if they used the space the way it was probably intended. We had 7 so it was a little cramped in the living areas that they didn't turn into bedrooms.
