Staying at Onur's place felt like being home. As others have stated here, Onur will treat you as a friend. He was always responsive anytime I communicated with him. He spent an entire day showing me around Istanbul, best day I had while in Turkey.
The apartment has a great view and although it's not in the center, I found the location to be ideal as there's transportation to take you everywhere, the airport is close and the neighborhood is safe and has all the stores you need.
It's also big and equipped with anything you might need during your stay.
Once again, thanks for everything, Onur!
