The house is very conviniently located between Harvard and MIT withing walking distance to both of them and only 5 T-train stops away from the Boston downtown.
Kevin and his wife are very helpful and responsive, and kindly answered all our questions.
The apartment is on the 3 floor, the rooms are not big and ceilings are quite low, but there are enough space for 4 people: two separate bedrooms, kitchen, living room and nice roof terrace. The destrict is very green and quite. We enjoyed our stay.
