We had a lovely time in Istanbul and Kadikoy in particular, the area is a nice mix of people, attractions and atmosphere. Kaya was there to greet us, bring a new kettle and even took us on a little tour to learn about nice places to eat and drink. The place itself was as described and is perfectly suited for a week or so with everything in the apartment working and within easy reach. We didn't have any problems, but I got the sense Kaya would have helped us if we had any issues. All in all, a nice place to stay in Istanbul.
