We stayed at Ali's place with my girlfriend for 5 days. The apartment is very cozy and spacious, equipped with pretty much everything you might need. Also we loved the location - just a 2-minute walk from Istiklal street and a metro station. Finally, Ali was very nice and super-helpful, providing guidance from the moment we booked our stay till our last day in Istanbul. Definitely wouldn't hesitate to stay at his place again.
