I would like to recommend this place to anyone who wants to visit Istanbul its located few steps from metro station which can take you almost anywhere in Istanbul in minutes , cevahir mall is 15 minutes walk and you can find anything at your footstep, shops and restaurants are open late.
Zeki is very helpful and managed to get us a taxi to get to airport.
If you have any question or any issue he is always there to help.
Probably one of my best experience.
