I can back up the good reviews, Lefteris's hospitality and the views from the house location are indeed the best! The house is unique and stylish, it looks new. Everything was very clean, and Lefteris left us a fridge full of food, including fruits and home-made wine.
We also received great suggestions for places to eat and for beaches.
A few more things might have been helpful to have in the house for guests: e.g. baking paper, extra towels, beach towels. Also mind that the en suite bathroom next to the bedroom has a foldable door, but you also have another bathroom reachable from the outside, it you need more privacy.
It's a shame there is only place to stay for two, so the price just for a couple is quite significant even in the low season. But you get nice interior, beautiful sunsets and peace on top of a mountain.
