Firstly I would like to thank Aykut for his hospitality and friendliness during our stay, being super responsive and attentive to all our questions and requests. Getting to the place was easy as we travelled from SAW airport and there are multiple ways to get you directly to Kadıköy, using both bus and metro was good and the airport and appartment are located in the same metro line just on opposite ends. The appartment is located approximately 4-5 minutes of a walk to busses, ferries and metro which is very convenient. Check in was seamless due to Aykut's clear instructions.
One thing to keep in mind as most appartments are a bit older in that side of the city, there was no elevator but for us it wasn't really a big deal. The appartment was exactly as described and seen in pictures, and the view of terrace definitely was a pleasant bonus, it was a clean and cozy little space which in time made you feel as if you are returning home. Also the location is lovely, having all needed around.
