Pros- clean, good amenities such as bottled water, cheap, easy check in.
Cons - Thin walls (heard people having sex at 3am in upstairs portion of house, and you can hear literally EVERYTHING), not in the best or most ideal location. Not close to Boston attractions - need to use public transportation or ride share.
Personal experience- considered leaving the Airbnb multiple times to find a new place to stay.
It's definitely a 'get what you paid for' deal. however, at the end of paying for transportation back and forth, we might as well have bought something at a higher price. Would not stay again.
