Piergiorgio's place was very nice. Originally a single apartment, it is now split into two separate apartments. We stayed in the Michaelangelo apartment. Piergiorgio and his family live across the hall, and they are prompt in responding to any questions or needs via the app. Piergiorio and his son Mateo greeted us and showed us maps of the area as well as identified the bus routes that would take us to the places we wanted to see in Rome. The apartment is located right next to a bus stop for multiple bus lines that were quite convenient to get to the Vatican and to the historic center. We slept well, as there was no street noise and the bed was comfortable. We got the Roma Pass for unlimited access to transit and that worked out well for us. The apartment is spacious, with a well equipped kitchen. We made a few meals there and wanted for nothing. The AC unit wasn't working for a few days, but as soon as we told Piergiorgio about it he contacted the repairman who came and fixed it. Piergiorgio and Mateo are great hosts and I would suggest anyone stay here if they are in Rome.
