I think it's sinful to use a specific place name because it evokes general wanderlust. Better to use something like Journey.
I like it as a Slavic name pretty well. It's been on my mind a little. I like the idea of pronouncing it like "MY-lun" in English and "MEE-lan" elsewhere.
I get the appeal. It's sort of an elegant word with the city pronunciation. I just don't think it's right.
