We had a long holiday in Istanbul and were glad to live in Fehmi's apartment, which has superb location with extreme proximity to the Blue Mosque and Aya Sofya, and very easy walk to other old town sights. The apartment is not big but has everything needed for the three of us, and the neighborhood is quiet. There are plenty of restaurants, four supermarkets, and one pharmacy nearby, which made the stay very convenient. Fehmi was super helpful, he arranged airport transfers at reasonable prices, and helped us with our luggage. During our stay, he fullfilled each of our needs as best and quickly as he can.
