I had a nice stay at Jonathan's house.
The location is great, it's easy to get to most places in Boston. The room was tidy and comfortable.
Jonathan was nice and responsive, and he allowed me to leave my bags after the check-out and come back for them later.
The room has multiple low ceiling corners, so I often found myself bending down when moving across the room. Be mindful that you'll be sharing the restroom with several other rooms, so you might need to wait for other people to finish their business.
Other than that, I haven't found any problems with the room.
