As a St. Louisan, let me just say I'd rather be in Bratislava or Bucharest, too! Sounds super fun!

But, I don't think this holds up if you discount the novelty factor. In purely economic terms, you'd want to be in Pittsburgh.

Having lived in Bucharest for most of my life (and in many other countries as well), I recommend Cluj if you really want to live in Romania. Bucharest has nice areas if you have the patience to look for them, but its traffic, noise, and pollution are unbearable
