The flat is very clean! When I arrived, I didn't even have to clean the dust (I ALWAYS have to do it, when arriving to a new place). The room looks cute and there's everything you need to cook in the kitchen. Everything works well. And the place is most convinient.
The only disadvantage was the heating system. Aydan allowed us to switch it on but it was still cold because, I guess, the radiators do not work properly. But with the heating on you can at least dry wet clothes, which is vitally important in Istanbul in December.
