We had an absolutely fantastic time staying at Ozlem place. She and her family went out of their way to make us feel comfortable and welcomed. The best part was the homemade breakfast on the terrace with a gorgeous view over the Marmara sea to Asia and the princess inlands. The location is right next to the blue mosque and a great starting point to explore the sultanachmet quarter (historical part of the city).
In the morning we could listen to the muezzin singing (if you close the window you can sleep through) of the hagia sophia and the blue mosque which are very nice.
They have been very helpful and kind in any situation and provided us with information and helpful recommendations.
