Beautiful/cheap Eastern European citytrip destinations

[Mein Fuhrer! I can walk!]

Hi everyone
I'm planning on going on a 2-3 day citytrip with my girl, I've got my eye on Eastern Europe for the old architecture, remains of the communist reign, overall culture and price. I've already been to Budapest and Berlin and really liked those.

I was thinking about mostly capitals like Prague, Bratislava, Bucharest,...
If some people could tell me wich cities are really worthwhile, I'd appreciate info and tips

Peace

vienna-bratislava-budapest are a really nice trip in my eyes.

I always had this idea in my mind that Eastern Europe is nothing more than a gray depressing place where some of my favorite pornstars come from.

the capitols that iīve seen so far (prague, budapest, bratislave) are really stunning and rather modern, the countryside can be a bit depressing, but with awesome nature sometimes. itīs like a trip 60 years back there.

the girls are a completely other story. so awesome.
