A porter greets you and helps your crew down hillside steps at this 500-year-old villa built as a defensive fortification. Living quarters now fill the historic watchtower, and terraced gardens color the hillside. Look over cliffs and sea from the infinity pool or rooftop daybed, then try the chef's menu in the formal dining room. Amalfi is a 5-mile drive, or you can charter a boat past hidden coves.
