Jack is the man! Out of the four hosts that I stayed with while in Istanbul for two weeks, he was by far the most interesting one. He didn't hesitate to introduce me to his circle of friends, which really made my experience in Istanbul a lot more colorful. He's in the heart of a cool neighborhood and close to all that one needs. His cat was fun to play with and his dog was well behaved. Plus, the mattress I slept on was better than my own.
