Gregorio's apartment was very nice. It is centrally located next to the Mercato Centrale and 5 minutes from the dome and Central Station. Gregorio waited for us until we arrived, at 22:30, he gave us all his support and was very understanding even when we left, when he allowed us to stay in the apartment until the evening because the plane left late. The apartment is in an old building, but with a lot of charm, fully equipped and with a very equipped kitchen! I highly recommend!
