This place is fantastic! Exactly what airbnb's are supposed be. The host was very helpful, and he had everything thought out very well.
He met us in Santorini, left us food and drink so we had something to eat when we got there (the nearest grocery store is about a 10 minute walk), let us take veggies from the patch he put in next to the house, pointed out the very delicious wild thyme growing everywhere (we cooked some nice meals there), and gave us connections into the small community living on Thirasia (he knows nearly everyone), recommending restaurants and explaining transportation options.
The area is so peaceful you can hear a bees flapping their wings. The abandoned cave houses surrounding the house are fascinating. And, the airbnb itself has nice, interesting cycladic architecture -- it has natural AC from being underground, but still manages to be exceptionally bright inside, thanks to some light shafts.
