John is a great host and extremely interesting person! The room is exceptionally kept and the bed is way more comfortable than one might expect from a mattress on the floor. We loved the location on a quiet street but just a short walk on a protected bike path from great public transit. We had a blast hanging out on the porches talking and enjoying the company. He was even nice enough to make us breakfast on our morning of departure. Truly a wonderful spot for anyone visiting Boston/Cambridge.
