Staying at Gian Luca’s place was a very positive experience. He welcomed us and showed us around at 6pm on New Year's Eve§ He was always prompt and efficient in replying to the few questions we asked. The appartment has a beautiful vaulted ceiling, it is spacious (we were 2 but could have easily been 4), nicely furnished and very quiet. It is also very central and easy to walk to the main monuments.
The internet is not perfect but I guess no one goes on holiday to be glued to their laptop.
A place I can only advise!
