Francesco was a very good host - personal check in from his colleague, and went above and beyond helping us make a restaurant reservation and an airport transfer on departure. Also turned up at short notice when we were accidentally locked out.
The apartment is spacious, clean, fairly quiet, and well equipped - even washing powder was provided for the washing machine.
Location in Trestavere was excellent - such a vibrant area and exactly where you want to be in the evenings for the range of great places to eat. The apartment is an easy walk to most of the main sites - 20 minutes to Piazza Navona, 30 minutes to the Trevi Fountain, St Peter's Basilica, 35 minutes to the Colosseum. Roma Termini is best by Uber/Taxi.
