I stayed for 5 nights at John's place. The place is nicely located in a quiet area relatively close to the subway (central station) and city-bikes. Technically you can walk to MIT/Harvard as advertised, but I would recommend the city-bikes/subway is you are in a rush. The restaurant next door was closed (November 2019), but there are other nice places around the corner for breakfast etc. The apartment itself is a bit older and perhaps not the coziest, but the beds were good and wifi works, so for a work trip this was a decent and cheap alternative. John was very responsive and the checkin was smooth - I would recommend the place for anyone looking for a convenient and relatively cheap option.
