I was coming to Cambridge for the first time, and needed a place to stay in for a couple of days to attend international orientation at the Harvard ed school before moving into my off-campus housing. Marion's space really fit the bill perfectly: close to a subway stop, peaceful area that allowed for uninterrupted sleep, a comfortable and tidy place, and a very gracious and understanding host. Marion's furry feline emperor was great company as well.
I would definitely recommend this airbnb to anyone who wants to stay in a relatively inexpensive place in tranquil environs while visiting the Cambridge/Boston area.
