The first rosy fingers of dawn creep up on the terrace of this cliffside estate and cast rays on Skaros Rock just below. Inside, classic Santorini architecture yields to modern design with high-contrast blacks and whites, geometric art, and angular built-ins. Dip in the heated pool, sip bubbly high above the sea, and test out the hot tub and sauna. Santorini Cable Car station is an 8-minute drive.
