Everything was exactly as Güner and Güven promised. A nice and very clean flat (1+ for the shower size), the best service of the two brothers, very quick and helpful responses to questions before and during the stay. The location has definitely more to give than its looks lead to think upon arriving. Try out the little streets leading from Istiklal street downhill towards Kabataş and Karaköy - a lot of nice little coffees and bars, wonderful for a chilled evening or a breakfast in the morning. I can definitely recommend to stay here.
