Mustafa is a really nice host. His house is so simply and comfortable. Small kitchen for you to cook if you miss your own food, eating in the dinning room with a beautiful sea view that made us feel happy. When we arrived, Mustafa gave us a warm welcome and introduced places that we could go. We postponed our check out time due to some issue. He help us to arrange and also help to keep our luggages. His apartment is the best I've ever rent. I strongly recommend you to go. Hope you can enjoy a nice journey in Istanbul. BTW, thanks Mustafa for everything he offered.
