Ioanna and Fotinos were very prompt with all communications. They organized a private pickup from the Airport and a porter down to the cave house. We didn't realize that the porter wasn't included in the €30. They do the hard work getting your bags up and down all those stairs.
The cave house is exactly as represented in their photos, although it's been a while since the roof of the pretty church below has been painted.
There was the absolute minimum utensils in the kitchen to put a meal together - but the view from the path outside was just as good as any of the packed restaurants. We loved having our private breakfast overlooking the caldera.
It's a great location, not just because of the view but also because it is a little away from where the crowds congregate. And there are crowds!
We really enjoyed a meal at Finos, great food and a lesson in how and why Santorini grapes are grown, and also a day trip to Perissa beach on the local buses.
