I had a good time at Iconic. The staff was very nice, fast check in and out.
The hostel could be a bit cleaner. It‘s also pretty noisy, you can hear the traffic very loud and even the people in the other rooms. The walls and windows are very thin. If you want to go out at night, Gazi is the perfecto area. Lot‘s of Bars, Clubs,… and I also felt save there. The metro station is just around the corner.
