Stelios was the best owner that I have never had. The apartment was excelent, very very clean and the views to the Acropolis from the roof of the building are spectacular. Stelios was very considered and friendly, we needed to leave the apartment later because our fligth leave Athens at 19:00, and he alowed us to leave the apartment later without problem.
I will come back to Greece and I'll contact with Stelios to repeat my stay in one of his apartments for sure!
