Pro: The actual room was perfect. The bed was surprisingly comfortable. I have a bad back and did not have any back pain from it. It was great having a private bathroom and your own small fridge. The room was very nice and clean.
Con: I had never been to Boston and did not know the area. In retrospect, I think it would have been nice to be able to walk to places to eat. That said the street was quiet and the price was much more reasonable so in the end it was maybe ok. I only say this so people know there is not much within walking distance.
The only real con, was the noise in the house. I am not sure if some people live there, but got the feeling they did. They were very loud until around 10:30-11:00. We were so tired it did not phase us, but as a heads up.
Make sure you do not put any food in the main refrigerator, I accidentally did and for called out by the “residents” there.
All this said the hosts were awesome. So friendly, fast in responding when we needed anything. I would recommend.
On a side note: if you have never been to Boston before and can swing it, I would recommend Lyft instead of renting a car, driving is challenging if from out of the area.
