The apartment is nicely arranged, new, clean and well located. There is a tram stop just across the street, mini markets within 2-3 minutes walking distance. It was easy for me to move around the city and in the neighbourhood.
I have to mention the host Okan here and his great attentiveness to any questions I had. He was very responsive and helpful every time I contacted him. He was proactive and really tried to make my stay as pleasant and easy as possible.
However, I feel obliged to mention here that there is an active construction site just across a little sidewalk. You can literally talk to the workers through your window or a balcony (which I didn't use at all for that reason). They worked every day (weekends included) sometimes even at night.
I understand that the owners have no impact on this situation, but I think it is only fair to mention this in the description of the apartment. I understand it is a temporary inconvenience but for me, it had a serious impact on my whole stay (two weeks) and Istanbul experience.
