This place is a real treasure. It's an updated cave home in the middle town of Firostefani, Santorini (Thira). The location is perfect, a little away of the crowds of Thira and right by the Firo square/bus stop.
The bathroom and the place is bigger than the pictures make it look. The view when showering alone is worth the rental.
We cooked breakfast in the mornings using local fresh produce and sat on the private deck. The kitchen is well stocked, there was even olive oil, spices, coffee, vinegar and a bottle of local wine.
Sunset from the deck is as good as Oia.
No air conditioning but the cave keeps the place cool. In September the temps outside were 80ish but the fan was enough for us. Also no pool and just a few rooms in this "hotel".
But this place has real character and is highly recommended.
