Our stay at Ayhan's place was absolutely awesome. The location is great, since it's less than 1 minute to Istiklal street and 5 mins to the metro station.
Ayhan really deserves a super host badge since he was the most awesome host I've met so far on Airbnb :D. He was really on point, replying to all our texts and questions and we even hung out one night, having a really cool time getting to know the Turkish culture through a local's eyes.
All in all, I can honestly reccomend staying at his apartment.
