Skip the tourist crush of summer and visit Santorini during fall to see its whitewashed houses stacked along the Aegean sea.For classic panoramic views, try staying at La Perla Villas, located in the village of Oia on Santorini's northern end. Also worth a visit is Fira, the island’s busy capital, which features bustling bars and restaurants along with narrow streets that wind along the edge of the island's caldera. Booking.com recommends spending the night at Lilium Santorini Villa, if you want to stay in the capital.
