I've used AirBnB in countless cities and I can honestly say my experience renting from Roberto has been the absolute best. The location is perfect - next to the Vatican and Ottaviano metro for quick access to the city. The apartment was impeccable and even included some free pastries from his bakery! We needed help booking a place after we extended our stay one night and Roberto went out of his way to help us. Great communication before and during our stay. Hosts like Roberto is truly what AirBnb is all about!
