We stayed a couple of nights at Stefano's apartment in Rome and overall we had a wonderful time.
The apartment is beautiful, roomy with high ceilings, and the balcony is a nice spot to hang out in the evening. It's located within ~10-15min cab ride from the center.
Stefano was very helpful. He offered us plenty of information about the city and transportation to/from the airport. He also went out of his way to resolve an issue that came up when we initially arrived at the apartment.
Highly recommended.
