As mentionned in previous comments, the photos are amazing but the reality in even better.
We were 3 staying there during four days and the house in unbelievably beautiful. The interior is really big and could fit no problem 6 people.
The double little terrace in front or the house was amazing, with an amazing view on the Caldeira. Waking up every morning to the view was something precious.
It is located in Imerovigli, a quieter place than Fira, but only 15minutes away by walking.
Every day someone would come to clean the house and change the laundry. It feels like a private house but with hotel services.
Olga and Dennis were really kind, providing us informations on the island and helping us to book boat trips and co, picking us from the boat and taking us to the airport.
We would TOTALLY recommend to anyone to stay there. It was an unforgettable experience. We already miss it.
