We loved our time at Katerina's place! It was walking distance from Oia, and there were several markets and restaurants along the way. Katerina was an excellent host who got in touch with us as soon was we booked the place, and offered to arrange transportation from the busy Santorini port (a must!). She also booked a catamaran tour of the island for us, which was the highlight of our trip. And the cave house was very charming :) We will definitely stay with Katerina again, and hopefully get a chance to eat at her family's restaurant too!
