We stayed at Katja's place for 1 night but it was a great experience!! The hosts greeted us so nicely with water and sweets and offered us free pickup and transfer to the airport late in the evening. Our room was big with small terrace overlooking the nice pool. In 10-15 min walking you are in Fira, otherwise there is a bus stop and scooter/quad rental outside the house. We recommend it! :)
