Summary: The basics, at the right price, and right next to the bus and the Blue Bikes.
I stayed for 3 nights while relocating to Boston.
Cleanliness: superb. They clean the bathrooms daily and I saw no signs or dirt or dust.
Responsiveness: good! Anne does not live on-site, but she or a family member is usually nearby to duck in and deal with anything that may have come up.
The room: spacious, good lighting, functional windows, ample closet, bookshelf to store your stuff on. I REALLY liked the room. Downside: the desk and chair are a bit clumsy. I don't recommend this space if you're planning of spending a lot of time working or studying in the room.
Kitchen: quite good! I hardly ever eat out, so it was nice to have a full-sized refrigerator and a reasonable stove and oven. For the price, I'm very happy with the kitchen.
Bathrooms: There are two bathrooms split among 4 bedrooms. It's ample apart from the occasional morning rush.
Downside: the neighborhood is a bit rough, and I don't recommend taking a long walk home late at night as it does feel a bit dangerous. If coming home at night, take a car or the bus (which drops you off VERY nearby, ~1 block away).
Recap: A great place to stay if you mainly need a place to eat, shower, and sleep. Just mind the rough neighborhood!
