I was there a few years ago and I do have some gripes about it - mainly the people.
Most are really nice, but there are so many slim balls. Even the visa guy in the airport wanted a kiss from my girlfriend before he would give her a visa.
The airport was full of the porters who expected a few quid for carrying your bags about a hundred meters.
I guess it is like anywhere else though, but it never gave me a good impression of Turkish people.
Enjoy!
