I cannot recommend more this place. I stayed 9 nights in Firat's apartment and it was much more than it is showed in the pictures.
Even if the weather in Istanbul was a kind of cold the apartment is absolutely well equipped, so I could stay warm and have a good rest.
There is a shuttle service to the metro station so it was easy to go by metro to the old city without spending a lot of money.
Firat was so helpful and helped me with all things I needed he even installed a mirror for me to practice my dancing performance. He waited for me until 1:00am when I arrived and helped me with my suitcases.
The area is safe, and there is a walk distance to Starcity outlet shopping center.
I didn't have time to go for my food but I easily ordered it to be delivered at the apartment.
The place is very quiet so, If I come back to Istanbul I would definitely stay in this place again.
