Francesco and his wife were great hosts. They were there to meet us when we called. Communication with him was fast and easy. He arranged for a driver to pick us up at the airport. Be sure to do that!! It was only 5 euros more than the taxi and he was waiting for us right outside the security exit.
The apartment was very clean, and we appreciated the treats he left to welcome us. The shower is small, but there is plenty of hot water.
The apartment is in a very safe neighborhood. We felt very comfortable walking there, even at night. The back side of the Vatican is 1.5 blocks away. The Ottaviano metro stop is a no more than a 10 minute walk. I would recommend this apartment.
