A collective in Florence has mobilized against overtourism, symbolized by key boxes on buildings, as Italy introduces a new law requiring property owners to verify tenants’ identities in person. The initiative arises from growing discontent with short-term rentals like Airbnb, where anonymous access raises security concerns. Florence’s mayor, Sara Funaro, supports the aesthetic aspect of removing key boxes from historical buildings, despite ongoing challenges in enforcing the law across the 640,000 tourist accommodations in Italy.
