Yüksel was a perfect host ! Always readily available and helpfull. As an example one night, as I was outside, I found out at 2am that I had forgotten the keys inside the apartment, Yüksel answered quickly to my distress message though and managed to find a solution for me.
Concerning the apartment the view on the Bosphorus is incredible, the bed comfortable as well as the couch, the situation is great close to taksim square and the ferries to cross the Bosphorus. There is a Carrefour convenience store at 2 min by feet wich is very handfull. To summarize, this is the perfect place to stay in if you want to visit Istanbul or even just remain in a calm and beautiful apartment.
