I went last fall. I stumbled upon some pictures of Kiev, and fell for the place. I studied the language for a few months before I went, I should have done more even though I spoke a little Russian, Ukraine is just enough different , So study hard, learn all you can about the places that you want to see. Some of the sites that I managed to get to were amazing to say the least. For me one of the hardest things that I had to do while there was to head back to the airport. I just didn’t want to leave so soon after getting there. So one last advice would be to give yourself at least 10 days there. There is so much to see and to do , I am planning a trip there for sometime in the next month or so.
