Gaye was kind enough to let me check in at 2 am as my flight was delayed and he stayed up till 2 am to let me in. The place was nice and good for solo travelers. There is a desk so I was able to work remotely during the day and the internet connection was reliable as well.
The flat is in the center of Kadikoy so everything is walkable, I love going to restaurants around and exploring the city. I usually walk to the ferry and cross the channel to go to the European side, it's still a walkable distance.
Overall, I had a good stay and you'll enjoy as long as you don't mind a little noise coming from the neighbours :)
