Some places seem to slow you down the moment you arrive. Monastero Santa Rosa was built for a quieter way of life, and centuries later that sense of calm still runs through the place. The atmospheric spa sits beneath original vaulted ceilings, drawing on Italian bathing traditions and the botanical heritage of Santa Maria Novella, while terraced gardens and an infinity pool offer wide-open views across the Amalfi Coast. For a programme devoted to deep relaxation, it's hard to imagine a more natural setting.
