Hakan was an excellent host! I needed a place to crash for a day long layover, and Hakan's place was a perfect location. Taxi price is exactly as advertised - 12 Lira. Hakan met me as the taxi driver dropped me off and showed the way to his apartment (beware - its up several flights of stairs!).
Room was quiet and private and clean. Hakan was more than willing to answer my questions, give travel info., etc.
Very positive experience!
