I stayed at Irem’s place for a week, I was in Istanbul for a solo adventure. It is on the 4th floor of a building w an elevator, very nice views and quiet for the most part.
The apartment was very clean and comfortable. The Wi-Fi worked just fine. I felt the apartment was a good value for the location. There were little stores everywhere, easy to get water and munchies. Also a short walk up the hill for restaurants, shopping, and the famous Istiklal Caddesi.
I recommend Irem’s apartment and would stay there again.
