Some hotels simply seem made for two. Monastero Santa Rosa has an intimacy that makes time together feel effortless. The spa is hidden within the old monastery walls, where thermal bathing unfolds beneath vaulted ceilings and couples can retreat to a private Spa Suite with its own rasul, steam room and garden terrace. With just 20 rooms and suites, four levels of terraced gardens and the Amalfi Coast spread out below, it's a beautiful setting for a few days devoted to each other.
