Zehra's home is in the hip center of Kadiköy and 10 minutes walking to the ferry that goes to the European side. It felt like a second home to me because she and her cat were warm-hearted and we became friends :)
You can have a good sleep, the shops around are always open, there is Netflix and there is the possibility to go for a nice walk/run along the seaside close to Zehra's apartment.
I can highly recommend it!
