This place is great! Don't ignore the instructions they send you on how to get to the place using public transportation. (That was my biggest mistake). It was my first time in Boston (which takes a while to get use to navigating), and following directions the host was kind enough to send me using public transportation would have made my trip much smoother.
The folks who run this place have a well-thought out system in place on how to run it. It's quite amazing, and everything you'll need is pretty much a no-brainer--very clearly explained. Labels everywhere also.
The best way to get answers to questions while staying here is to message the host on airbnb--and they respond rather quickly. Rarely did I see the host at all.
I plan on staying here again on my next Boston trip.
