Ukrainian girls are probably the hottest around
BUT don't even think about taking in camera equipement - I have been 4 times, and 3 of those trips something was stolen from my luggage (and padlocks cut off bag!). Luckily wasn't shooting just there on hols!
And as others suggest Kiev is not cheap, and you would need a local speaker as well.
And even though the girls are amazing, the hassle of shooting there for most apart from locals is too much, I would head to Prague or Budapest where the girls are also amazing - much better than most UK girls
