Sinan was available to all our questions, and was very pleasant (we only chatted with him). The place was very nice, kitchen and bathroom was renovated and it was great, and the place was in a good location, few minutes from the Opera.
The kitchen was small but really nice, and comfortably equipped (oil, spices, dishes, etc.)
The cons were that the place has little mold on the on the corners of the walls. It was because the apartment was very cold with no available heating system, so the air felt wet.
Sinan explained that the apartment has a main heating system, and that it will start working only on a specific date in October.
Also the sofa (that was also a bed) was a little dusty.
Other than that, the apartment was lovely and the communication with Sinan was great. Thanks!
