Backlit stairs lead past local white limestone walls to a private dock below this spa-like modern villa on a protected inlet of the Adriatic. Start your day in the steam room or sauna before a dip in the infinity pool, then slip on a white robe and sip espresso on a balcony lounger. A limestone wine cellar and dramatic light fixtures liven the crisp interior, and Sumartin Beach is less than 2 miles away.
