Chiavistello is an Italian self check-in and remote access platform designed for B&Bs, short-term rentals, and property managers. It enables hosts to let guests enter independently at any time by sending access codes via a simple message—no guest app required—reducing waiting time, operational costs, and the friction of key handovers.

Beyond door access, Chiavistello positions itself as a broader hospitality operations toolkit: it supports connectivity with OTAs and channel managers, helps streamline guest check-in bureaucracy (including "alloggiati" guest registration workflows), enables payment requests, and provides access notifications and real-time alerts in case of issues. Installation is described as internal to the apartment, avoiding changes to shared building systems and typically not requiring condominium permissions.
