I had a great time staying in this apartment - its perfectly located in the center of Kadikoy but at the same on quite street, so nothing wil disturb you. There are lots of cafees, restaraunts and shops nearby. Ferries and buses are also in the walking distance.
The apartment is beautifully decorated and feels cozy and comfortable in every apsect.
Its also great for remote working - there is big table and internet speed is great.
Serhat's friend Hilal was very friendly and provided me with all required information about my stay.
Highly recommend!
