My friend and I had a wonderful stay at this 2-bedroom unit at Kimberly's. It is on the main floor (so don't have to lug all your luggage up the stairs), with the larger bedroom on the second floor (Philadelphia style). The apartment is fully equipped with new washer & dryer and water & goodies for some breakfast.
Since the houses are old in the Cambridge area, the floors are squeaky...but the place is very clean and bright and near some good eateries and groceries. It is about a ten-minute walk to Porter Square and not too far from Harvard.
Kimberly was very easy and quick to communicate with, and we had a great stay at this lovely apt. to relax between our work. Nice and safe neighborhood!
