Hilton Waldorf Astoria Rome Cavalieri Hotel. A scent for every season. Surrounded by a six-hectare private park covered in Mediterranean vegetation and overlooking the Eternal City, the Hilton Waldorf Astoria Rome Cavalieri Hotel offers an unparalleled experience. Integra Fragrances has developed 4 olfactory identities to welcome guests with a scented novelty with each change of season, and a Christmas creation to delight them during the holidays. The halls, elevator areas, common areas for access to the fitness room and the SPA are scented thanks to our technology.
