Ioanna's home is truly lovely and authentic! Right on the side of the lovely Santorini Oia cliffs, with priceless views of the calderra and sunsets upon your own private rooftop terrace (while watching the crowds fight for a good spot all around you). The home has been in her family for generations, and shows the love of a family treasure. The fun authentic cave-like architecture made it a special place to be, and enhanced the authenticity of the visit. However, you had all the modern conveniences you could want - A/C, small kitchenette, nice large shower, etc. They met us at the free parking area and helped us with the luggage. Then offered a small bottle of wine from their own vineyard for us to enjoy.
The only thing, and this is true of most any place you'd stay in Oia, is that you need to be able to navigate the steps to the house and from the house to restaurants, the village, etc. But if mobility is not an issue, than I would highly recommend this place!!
