Our stay was all in all very good. Gianluca provided our very late arrival (02.00 in the morning) was perfectly organized. He booked a taxi to pick us up and his collaborator Marco was waiting for us in front of the main entrance. The house is not very big, but beautiful, very well organized and perfectly clean. The terrace is fantastic. The house is in the center of the city, in the most upscale neighborhood, so one can walk to many monuments and go around in the evening without feeling insecure.
The only little problem we had was that there has been a gap in communication two days before our trip. It was solved at the end so no real effect in the organization of our stay.
