Deniz is a fantastic host very hospitable and will go out of his way to make you feel welcome, when he found out that I was arriving early, he let me check in early. The flat is clean and new you also have 24hour security, the location is great right in the middle of the Istanbul you have a nice coffee shop in the building taxis are easy to find, and there is a nice shopping center wright next door (Airport mall) with restaurants and a big supermarket. The metro station is about 10/15 minutes' walk and there is a bus stop in front of the building, I would defiantly recommend Deniz's flat.
