Stayed at this airbnb during our 5-day trip and enjoyed it! The location was superb - walking distance to so many places (the wharf, aquarium, quincy market, fanueil hall, downtown crossing, boston commons, metro station, Target, Whole Foods, and a bunch of cute coffee shops).
The self check-in process was very convenient. After filling out some basic logistical information, they provided us with two codes (the main building door and the door to the room). There are a few flights of stairs so make sure to pack light. Communication (via chat on airbnb's platform) throughout the trip was quick.
The pictures were accurate but made the place looked bigger than it is. Not terrible but definitely was a surprise compared to the pictures. The bathroom sink was super narrow and practically useless (couldn't really wash your face there and the hand towel rack for some reason hung over the sink). So we ended up just using the kitchen sink for everything. There were basic kitchen appliances but there was no cooking oil, salt or pepper. The pan was okay but it was too big for the burner.The AC started dripping water on our second night and we had to turn it off. The service was great though, they sent someone over the next morning. However, the issue wasn't fixed entirely so they sent someone over again the next day (it worked).
Overall it was a great experience. Definitely would recommend if you want to live downtown for a couple of days!
