We had a great time at Caterina's apartment. She provided great advice for traveling to/from the airport without even asking. Her mother met us and showed us around the apartment, offering helpful suggestions of places to eat locally. Trastevere is a great location as you can walk to all the main tourist attractions but there are plenty of bars and restaurants on your doorstep. The apartment was clean and comfortable, and we would stay here again on our next visit to Rome.
