great city... I love it...
I loved the culture in it, the blend of Europe and Middle East in one place..
I loved the nature... the rivers, the trees...
I've been there late september and the weather was simply amazing..
I loved the food... the bazaar, the shopping...

BUT
Though it is a big touristic destination, I didn't find Turkish people there to be friendly or helpful, they were rather on the aggressive side, this is why I am a bit reluctant to go again with a kid.
