I had only contact to Yigit, not Ömer. Yigit is a very friendly guy. He was trying to help us as much as he can. When ever I contacted him or asked something he was answering most of the times directly.
Therefore I would give Yigit as Person itself really 5 stars.
But the house would not deserve 5 stars. First of all it is the same as on the picture. But we had some smaller issues with the toilette, which where honestly also solved at the same day by Yigit. So my suggestion is that these issue may be solved before the guests arrive next time. In general I would definitely try further apartments from Yigit.
