location, location, location. Kris' apt has the best location at Harvard neighborhood, especially good for anyone whose travel will be mainly around the campus.
You can also easily get access to any restaurants, supermarkets, and schools.
it is at the ground floor so that you can hear the subway groaning but it was not bothering for me.
the only problem is communication. when we arrived, the masterlock code was not updated on tenant manual and we couldn't get the keys. we waited for half hour until she replied my message and sent new code. Kris said she left a message via airbnb but i cannot find it. might be some airbnb technical problem?
for the rest, it is pretty good experience.
