We stayed for a week in Dundar's apartment, and on arrival he greeted us and gave us a quick tour of the apartment and a brief rundown on the area- good places to eat locally etc. He also had a guide book for us to use. There were four keys available for our group and all had a metro card attached which saved us having to get them ourselves. We had a couple of questions throughout our stay and Dundar was very prompt and helpful, recommending a hammam and helping us with logistics. A great host!
