ISO 21620:2021 specifies equipment and service requirements for heritage hotels - licensed accommodations established in historically or culturally valuable buildings (e.g., caravanserai, castles, historic houses). The standard focuses on providing quality services in a traditional style while preserving the building’s historic character. It covers conversion constraints, rehabilitation and maintenance planning, and the harmonization of furniture, décor and service provision with the hotel’s historical period.
