I stayed with Tunahan bey for 3 weeks.
The location is close to the subway and there are many small shops nearby. My favorite AVM Zorlu is in a couple of stations.
The apartment has been well renovated, in new house with an elevator, and it's very warm, which was important to me. I live in an equatorial climate, and I get cold when the temperature drops. You can cook yourself, or order food from nearby restaurants. There's all stuff for cooking in the apartment.
All existing shortcomings were eliminated by Tunahan bey in a short time.
In general, I'm satisfied with my stay in his apartment. If you are traveling for work, a very good option for you.
