Charles and Christiana went out of their way to make me comfortable and to take care of me. The room was sufficiently big; the bed was comfortable; the house and space is not elegant, but it is serviceable. I had my own bathroom; the water in the shower could have been a bit hotter, but it was fine. I was in Cambridge during a snowstorm, and Charles and Christiana literally went out of their way to ensure that I got parking and got what I needed. They couldn't have been more accommodating and gracious.
