I was living at Marzio place for 4 days and the Apartament 'I DUE SOLI' has my full recommendation. The apartament is really great - clean, big , full equipment (kitchen, iron, access to WiFi, etc.). It is close to the railway station (about 10 minutes for a walk) and to the center.
Marzio is really nice and helpful person, he gave us a lift from and to the airport, advised on where to eat and what to visit.
Thank you very much Marzio and I hope see you soon:)
