The place is really central in the region of Kadıköy, the appartement is really cool and cozy. It's quite loud because of the cafés and the restaurants but untill a normal hour. The host is really helpful and he responds quickly when you need something. Generally i will suggest it to anyone who would like to stay in the center of kadıköy, it's totally worth the money. The only disadvantage I could mention is the wifi but i think that, internet is a general problem in Turkey.
