Stayed for 3 months as a Koc University exchange student :) If you’re not picky about staying in a regular apartment (lived in and quaint, but otherwise clean and full of amenities), it’s worth as much as, or even more, than it costs. Zehra was a good host too, and very willing to help with any issues I had during my stay. The cats are also very affectionate.
I had trouble climbing the hill at first, but you get used to it and it’s a good workout.
