Ioannis is an incredibly generous host. We met up in Athens for a drink and a chat about Ioannis' recommendations for places to visit in Oia. Ioannis also thoughtfully arranged a transfer for us and left a mobile phone at the house in case we needed to contact him. He's an absolutely perfect host!
Of course the cave house is amazing, and a real steal for the price. It is peaceful in the morning and late evening, and well positioned to enjoy the sunset.
