Everything were fine.
Kadir and Alper are careful hosts, very pleasant to deal with. They did not disturb us during the stay, but helped with any question (like add kitchen towels, a pot or really BIG fan).
The flat is really cosy, in Middle Earth style. The lamps as a separate art form :)
The area is silent, Migros supermarket is in about 7 minutes, metro Osmanbey green station is in 5 minutes. There is also a turkish sweets bakery near. You can buy the famous chestnuts and baked corn on the way from the supermarket
