Oia is still quite crowded this September, but Rena made it so easy to check-in to this wonderful cave apartment right under the iconic church and over the caldera it completely made my trip to Santorini so sensational! She arranged a great driver to pick me up in the bustling new port when my ferry arrived, had a friendly porter carry my bag down the fairly long flight of steep steps to the house and show me where everything was. The housekeeper is really nice and everything for Continental breakfast was provided. As others have mentioned the view from the veranda is breathtaking-you won’t want to leave!
