We've had the opportunity to visit Boston a lot lately, since two of our kids are in college in Boston. Since the hotels are so expensive, we've stayed in a lot of Airbnbs across Cambridge. As a whole they've been great.
Robert's place was nice in that it was all my wife and I needed - not too large, but with plenty of space. It is on the third floor so very quiet. Also in a nice location with nearby shopping, restaurants and other amenities, yet close enough to MIT to walk.
