Booked for four nights and then extended for another two nights (due to another conference) -- I would definitely book this place again, when I come up to Cambridge/Boston again. Close to both Harvard and MIT, and a bus station that easily takes you to Boston. Subway station is within walking distance. The host is very responsive and provided timely help whenever we needed, even at around 10 PM. The place is very, very clean. And the kitchen is easy to use. Definitely one of my best urban AirBnB experiences! Highly recommended!
