This cave house is lovely. The kitchen is fantastic and very well stocked with appliances and the host was kind enough to leave a welcome gift of fresh peaches, plums, mini croissants and wine. The space is larger than it looks from the photos and the furnishings are nice and homey. The bathroom is a bit quaint (the shower is stone and has an old stone water spout which adds some character) with some nice toiletries provided as well as a washing machine. The outside space is absolutely lovely -- it's a beautiful place to have breakfast in the morning or some wine in the evening. Obviously this place does not have the caldera views, but if you're looking for a unique stay this was great
The hosts were kind and though they didn't speak much English, I was able to communicate through Aris who helps manage the reservations and who provided ferry and airport pick ups and drop offs for a reasonable cost; he also organized ATV rentals for me which dropped off and picked up the vehicle at the house - very convenient. Chatting with Aris about Thira was a highlight of the stay.
Two minor issues. The airbnb is a bit far from things so you'll definitely need a vehicle. To walk to the nearby intersection with some restaurants and a grocery store takes about 10-15 minutes. Getting to Fira by ATV is about 10 minutes and to Oia about 35 minutes. Airport is a 10 minute drive. The second was that the wifi was very slow and most of the time it did not work. Given that it's a cave, don't expect to get any phone signal while you're inside as well; I also had zero signal with Vodafone outside the room as well. For someone working from home, this became a pretty big issue for me.
