Rodoula was a great host, who arranged our transport both from and to the airport the moment we arrived and the time when we left. She made useful suggestions for our tour and was readily available. The spacious and well-maintained cave house was a unique experience by itself. It's located within walkable distance from the bus stop "Zotos" Bakery, where the grocery stores and restaurants, etc. are nearby. But the house has no address because street name and number is not used in Santorini--surprise! So better remember your way back before you get lost. I highly recommend this hospitality.
