Carla & Steve's place is a great value for the Cambridge, MA area. My room was quiet, clean, spacious, and the host is very easy going and helpful. My room had AC, ceiling fan, opening skylight, etc. - even had a fancy espresso/coffee machine stocked with several selections. I would recommend it, particularly for easy access to Harvard and Tufts, and also the entire Boston area at the nearby Davis Square subway Station.
