Damiano is easily one of the best hosts I've ever had the pleasure of staying with; from the moment I met him, I felt warmly welcomed. He very kindly made me coffee in the mornings, gave me grapes grown on a local vine and often sat down to have a chat with me. He really is an exceptional person, and staying with him made my time in Rome so much better. His son Pietro is also very friendly and lovely, and was great to talk to.
The apartment is well-furnished and tidy, and the bedroom is spectacular: it's of hotel quality, and even has its own balcony. Public transport is within easy walking distance, as is a variety of supermarkets and restaurants.
I can't express how glad I was to stay with Damiano in so short a review, so the best I can do is tell you to book immediately and prepare for an Airbnb experience like no other.
