Communication with Cengizhan&Ceren was very friendly and smooth and Cengizhan was waiting for us upon arrival.
The apartment is spacious and clean though I would invest some more to make it better functioning. A great grocery shop is near by.

If you're young and enjoy a nice place with great hosts, the place is recommended.
