The women are really great, that's true.
I am from Poland too by the way. Definitely St. Petersburg is a place worth going to. Cracov is really nice - everybody loves it and it's perfect for a couple of days, there are also interesting things to see outside the city. In Ukraine - Lviv no doubt ( Minsk is nothing special in comparison).
Also Chernobyl is no longer radioactive, my friends visited and they were amazed.
I didn't like Budapest that much, I think it's kind...
