Claudia was an absolutely lovely host. She gave us lots of good tips, helped us to arrange taxis to the airport, and was up herself in the middle of the night to make sure that we got picked up. The apartment itself was basic, but the bed was really comfortable. What I would warn others about though: there aren't any real curtains, and it's very noise at night, so we did wake up a few times. But then you are in the middle of Trastevere, a great neighbourhood with lots of bars and restaurants.
