We had a great stay at Eyüp's place.
The flat is in a new building, it was very comfy and felt like home. There were all the necessary appliances and more. Internet connection was always great, allowed us to do remote work without any problems. Bonus for a few cute cats constantly watching you through the windows :)
The area is relatively quiet and modern, but be prepared to walk uphill.
There were a few of the owners belongings in the flat, but it didn't bother us at all.
