Great value!
Marie was a very good host. She responded fast and kept us stocked with cleaning supplies.
The room is small, but has two walk-in closets and a comfortable airbed. The kitchen is pretty big and well equipped for cooking. The living room has two sofas and is also spacious.
I commuted daily to Cambridge, which is about 45 min total per way. You can walk 10 min or take a short bus ride to the next T station, and then take the Red Line from there.
Overall my stay here was comfortable and affordable.
