The cave house is beautiful and gives a feel of what they were like to live in. Views from the house are also exceptional! However, Exo Gonia is quite a distance from Thira and Oia, and taxis in Santorini are very expensive. Would recommend hiring a car. Also note, card cannot be driven within Exo Gonia, so need to park nearby then walk to the house. There are no convenience stores in Exo Gonia.
