The probably most important point: Very, very nice people! Bob and Yvonne are great hosts, very lovely, and will make you feel welcome. If you do have any questions around where to find something, how to get there, or what to do in Boston they are a great source.
The house is nice, the room is fine as well.
Everything that you need is going to be there, including a washing machine.
The neighbourhood is not my favorite, especially as connection to public transportation could be better. There are regular busses throughout the week, on weekends you will have to plan some time to get Downtown.
