Great hostel. The staff (Ede, Elif, etc.) is super attentive, friendly and helpful. They go out of their way to make sure you are comfortable. They are super flexible and understanding (let me pay for the room the day after, early check in, etc.)
Location is great, atmosphere is nice with friendly people. And they have a cat in the hostel! Hunter is his name.
Only complaint I have is that beds should have curtains and my first room smelled a bit
