Positives: This is a fantastic location, especially if it's your first time in Boston and you plan on doing the Freedom Trail (it's right outside your door). Communication with the hosts was great, they always answered almost immediately and allowed us to check in early around 2PM for a $50 fee which was great. This is a perfect airbnb for 2 couples traveling together, since there are two almost identical rooms with a large living room/kitchen area and a nice bathroom. The price was much cheaper than hotels or other airbnbs in the area that I could find. The apartment was very secure, as there was a code to get into the front door, and then another code to get to the elevator lobby.
Things to note: Would like to start off by saying none of these things were that important to us or took away from this being a great place to stay, but thought it was necessary to mention in case it's important to future guests. The listing says "large windows that let in lots of natural light". This is misleading- there are 3 large windows but they face into a small opening with other apartments surrounding it so there was essentially zero natural light coming in the apartment. The lighting in my bedroom was not great, and the other bedroom did not have a mirror so it made it a little difficult to get ready without the natural light. The beds were not super comfortable but they did the job. We didn't experience any noise until our last night, but that night the people above us were up pretty late and it sounded almost like they were in our apartment so I think the floors or walls must be pretty thin.
Overall, I think this airbnb was a great deal for the price and we would stay here again.
