Dimitri and his wife are very kind and helpful. Also the breakfast is HUGE (coffee/tea, toast, marmelade, ham, cheese, yogurt and honey, fruit, croissant) and cheap.
Just one thing: you might ask Dimitri before your arrival to get the right adress, the localisation on airbnb is not ok.
We recommand to stay at this place, it is near the beach, you can reach Oia in 45 minutes in quad.
