The listing was as described - this is a typical Cambridge home very quiet, at least on a weekday night, and super-convenient if you have work in the area. (The Uber fare to Kendall sq. is about 6 bucks). The home is also very close to a bus route.
The home and room itself was quiet, neat and clean - no complaints!
The window mounted AC unit does take some getting used to, but 97% of the homes in this area have this. (and it's needed in Boston probably for all of 4 weeks in the year!)
Jason was a thoughtful host - had a parking tag for me, and provided valuable tips on getting around.

Would stay again, if in the area.
