Munich (not "Muenich"), clean streets? Well ok, everything is relative, but even in Munich there is a lot of garbage and graffiti (although I concede that the graffiti in Berlin is better than in Munich, because in Munich most of it seems to be because of the rivalry of the two local football clubs). But, to also say something positive: Munich wouldn't be so expensive if it was as undesirable as you describe it. And yeah, Berlin is desirable too, that's why it now gets gentrified too. That's life!
