You sounds like a true Ukrainian - "only 300 km apart plus roads..." and plus boarder, it may takes a halp of day )))
I moved because of my husband's work. He wish he'd move to me, but Kyiv was the only town he can work in Ukraine.
It's so nice to hear you enjoyed your visiting Kyiv! If you ever want to come again, I'd be happy to meet you and show you the town from the sight of locals ))
