First stop would definitely be Kiev, Ukraine because I lived there a few years ago and left part of my heart there. After that I really wouldn't know - there's so many beautiful places but one month wouldn't be enough to experience them properly; Tokyo, Moscow, Anchorage, Prague, Bejing, Dhaka... I could go on for quite a while. So if I'd really have to pick one then I'd stick with Kiev since I know what I'll find there will bring a smile to face, perhaps even tears of joy - the tiny things that I find beautiful; I prefer that over all the places that might put me in awe.
