Dilek was a super warmly host. The communication with her is to any time easy and you can ask her any recomodations (especially for good food). She looks after you so that you‘ll have a fantastic time in Istanbul.
The appartment is situated very central in a nice neighborhood with a lot of nice cafés, bars and small designer shops. The rooms are like described, cozy, clean and furnished with a lot of taste... there is nothing more to tell. So go for it and book it!
