Ali was very friendly and careful person and flexible with check in and check out. My friend and I stayed a week in his nice apartment. The apartment is very clean, very good located and you feel like in own home. The apartment is wide and comfortable with stylish furniture. Furthermore, there was a soap and washing machine which is super important thing for a traveler. If you have heavy rain in Istanbul you can even stay in Ali's flat and watch Netflix or play Playstation :). Very good conected by metro lines (M2, T1) with Historic Areas of Istanbul. Sometimes we heard a little noise from the nightclub in the street , but we didn't mind . I can highly recommended this place.
