Firat and Ozan are great hosts. Very easy going and fun people. I spent a month in the apartment without any problems. Firat is an architector and the apartment has a cosy and minimalistic style yet it has everything for your needs.
The apartment is located in the heart of Istanbul where you can enjoy the real vibe of Turkey.
What's great is that the apartment's windows are facing a backyard so it is super quiet in the apartment while when you go outside, you join the fast rhythm of streets immediately and learn new things about Turkish culture.
Firat and Ozan helped me with things and were making sure that my stay was great. Recommend!
