I ve recently visited Boston with my bf and we were hosted by John( his brother was away). He was very nice and friendly and made our stay very pleasant and comfortable.
The apt was clean,we stayed in a small room with the queen size bed but had an acces to all parts of the apt so it felt pretty homie.
The neighborhood is old but interesting- so rounded with trendy,cool bars and restaurants and also has a pretty easy acces to the downtown area.
All in all we had a good time staying with John,I would gladly recommended.
