I would thank Ozkan for being so kind towards me and my family. I stayed at his place 6 nights with my parents. Everything was as planned, so nothing unexpected happened. We were just a bit pity that Ozkan couldn't spend time with us. But we surely felt as in our own flat. The main things for me: bathroom, toilet, and the heating system were good and clean. The only thing under my expectation was location. I thought it to be very close to the center that I won't even use any means of public transport. But we had to use them in order not to waste our time on the roads. All in all, everything was OK. I would recommend Ozkan's place for staying in Istanbul.
