i used alot airbnb because i travel alot and about serdar i can tell, he was awesome and he was best host in my all experiences. he is real gentleman and he came to me for help and bring me home and he is fluent in english. his place had a nice view of heart of istanbul and his place is in center of city and so, center of everything and you have access to all kind of public transportation. his place is close by major mall and starbucks branch and all kind of restaurants by walk. my experience in serdar place was the best one. thanks serdar
