Our experience with Giancarlo was very good - the apartment was 5 minutes walk from the Vatican, in a nice neighborhood. The place was clean and with all the necessary amenities. Giancarlo was very attentive to our needs, replied very quickly to every question we had, and provided us with a nice list of recommended restaurants, he also tried to help us when we had troubles renting a car. We had a very nice time at the apartment. One minor thing - there is no view from the apartment but there is a magnificent view of the dome of S. Pietro from just across the street.
