We had such a lovely stay at Alexandra's cave house. It's such a lovely place, was super clean and Alexandra was a great and helpful host. The meet-up worked well and we had no problems at all during the stay.
Finikia is a lovely little village, all pedestrianised (make sure you don't take a heavy bag with you), about 10 mins walk from Oia. Other parts of the island are accessible by taxi, bus or there is a spot nearby to rent scooters, quad bikes and cars. We were just sad not to have stayed longer.
Thanks Alexandra!
