Petros is a really really really nice host. I have never met such a nice and friendly host like him. He drove us to introduce the spots, market, restaurants which are near his house on the first day. And he offered us some cookies, wine and homemade tomato pies which are really delicious!!! In addition, the information he gave us was so useful. The places he recommended are so beautiful. What's more, he helped us to rent a car at a good price. And before we leave, he sent us some lovely gifts which we love very much! In a word, the most precious memory in Santorini is living in Petros's house!!
