Via Caiolo, 204, Roma

This is within the built-up area of Rome on the Tyrrhenian side of the metropolitan area, with the Tiber as the main river system and the coast at Ostia within the local radius. Daily surroundings here are urban districts, arterial roads and suburban fabric rather than a distinct rural or scenic landscape. Rome itself has first-rank monuments, museums, major services and an international airport, and the historic centre is UNESCO-listed, but the urban cap applies because the cluster sits inside a city far above 50,000 residents.
