We had a great stay at Sharon's place. The house is very conveniently located between Harvard and MIT, and 20 min from downtown Boston.
The apartment is up a flight of stairs and very charming. A good sized living room, a good sized bedroom with two queen beds, kitchen and full bathroom on the main floor, and two more bedrooms, a half bath and laundry on the top floor. A clothes steamer was helpful.
Parking on the street in front was sometimes available when we got back in the evening, otherwise we parked in the driveway on the side where a spot was reserved for us. We had a big SUV and had no problem at all.
There is a park with nice grass and a playground across the street which was nice, especially if you have kids.
A Wholefoods, several great pizza and take out places were within a 10 min walking distance.
