We stayed at Hector Caves for a week, and we had a great time! Giannis was helpful in arranging transport from the airport to the post office near his place, and Dana and Dimitrius were waiting to meet us to help us with our luggage, show us the way to the flat, and give us tips on local restaurants. Hector Caves is very conveniently located within Oia--just a few steps to the popular sunset-viewing spots, close to all shopping and restaurants, and the Atlantis Dive Shop, for scuba diving. The terrace has a beautiful caldera view with a table, chairs, and umbrella, perfect for lounging. It was still a bit cold to get in the jacuzzi. On recommendation from Giannis, we rented a car so we could explore more of the island.
