Kerem's flat is very nice and clean. It was perfect for our short stay in Istanbul. It's biggest advantage is its location:Besiktas, a vivid modern location not far from any other place a visitor would like to visit. The flat is very nice, probably a bit smaller than what it looks in the photos, but still spacious enough. It was perfectly clean and tidy. The bed is comfortable and the bathroom very nice. The kitchen is a bit small and underequipped, in case a visitor wants to cook- but at least this was not our case. Ibrahim, Kerem's assistant is very gentle and responsive, genuinely caring for the visitors. Kerem, that I only got to meet upon departure was also very gentle. Overall I recommend the flat, especially for couples visiting Istanbul for a short time.
