John’s place is at a great location in Cambridge. You can go to Harvard and MIT by walking. There’s plenty of options of where to eat and the subway station is pretty close. If you’re looking for a place to stay one, maybe two nights this can work for you. However, if you have any dust allergies you might want to look for another place as the house is old. The house could use some renovations and more detailing on the cleaning but is not bad. During the night the room can get really hot but opening a window helps. Also, the street can get noisy at night and you might hear rats fighting. I would recommend having sleeping masks because of the sunlight early in the morning if you like to sleep until a little bit later.
Anything that you need (fixing, cleaning, something from the kitchen, etc) John would provide and he usually responds very fast.
