Kaya was a great host, he took the time to show me around the local neighborhood and suggest a variety of stores and restaurants in the area. Moreover, he was very responsive and when I accidentally locked myself out he helped me get back inside in a short period of time.
The flat itself is exactly as pictured and is admittedly basic and no frills. If you intend to do a lot of cooking then it is probably not your best bet as you have only the single burner and a small area to work with. If that isn't a problem for you then you would be hard pressed to find better value for your money.
The neighborhood has just about everything you could want within a block or two inclusive of several grocery stores, clothing stores and restaurants. It is about a kilometer from the kadiköy metro stop and thus a short trip to a hyper-market which augments anything the smaller grocers in the immediate area might be missing. The reputation for kadiköy is that it is mostly a residential area which is true but the street level area are all shops, so there is plenty to explore and discover.
All in all it was a very good stay that I would highly recommend for anyone looking for a basic flat at a good price with a great host.
