Sersha is a tremendous host, he is overflowing with the Turkish hospitality that you hear so much about. Although I didn't stay there long I will most definitely stay there again when I next visit Istanbul, hopefully for longer next time. It is in Kadiköy which is on the asian side of Istanbul and a much less touristy area. If you want a uniquely local experience of turkey and in particular Istanbul this is the place to stay. My last visit to Istanbul I stayed next to the Galata tower, I can safely say that this stay was a much more fun area to be in. Loved it, and will definitely stay there again once I get the chance.
