Aziz is a very nice guy. the apartment is 10 min walk to ortakoy one of istanbul's must visit spots. where you will find a lot of shops, restaurant, caffe and bosphorus cruises. But it's located on a steep hill so expect to climb long stairs which is maybe not suitable for elders and small kids.
The apartment was clean, there is one Queen bed and the rest are sofa beds which is maybe not comfortable for adults. The weather was warm (end of July) and there was only one fan which is maybe normal in Istanbul.
