Stefano and Valeria are amazing hosts. They arranged airport pick up for us. Upon arrival, Stefano helped carry all our luggages up the three floors (all by himself!) while Valeria gave us a very thorough briefing of the city, the area and the apartment. We tried out all the food places they recommended and love all of them. The apartment itself is very centrally located and it has everything we needed. We walked everywhere including Vatican City. The only minor downside given the central location is that it can be a little noisy at times at night.
