Maria was a good host. The place was clean and comfortable.
The redline was down all weekend, so getting into downtown Boston was difficult and very time consuming since we had to take busses the whole way.
As others have said, there are five rooms which can be rented out by other guests and all guests share one bathroom. It was not a big problem, since only a couple of rooms had guests, but if you come at a time where all rooms are full, you may wind up waiting to use the bathroom.
