We loved it! We are two friends in our mid thirties who went for a long weekend to visit a friend who's studying in Cambridge.
The house is in a nice, quiet neighbourhood within easy walking distance of Harvard Law School, Porter subway station, there are nice restaurants and bars close by on Massachusetts Ave. and Beacon st. The 3rd floor suite is extremely cosy and we were surprised by how spacious it was, and well stocked with amenities. Susan is a wonderful host who provided us with great tips and helpful advice, and we really felt at ease and at home. The english muffins and coffee were fantastic as we arrived late and didn't manage to shop supplies before our first night.
We will definitely try and stay there again if possible, and I would highly recommend to anyone who does not have a problem with climbing a couple of flights of stairs. What a great place to relax after a long busy day of sight seeing or shopping. We miss it already.
