maybe everyone in Russia will have indoor plumbing
Funny coming from a German.
There's not a single city in Germany that can be put in the same rank as Moscow or St. Petersburg.
In comparison to Moscow, Berlin is small, dirty, and grey. The Tiergarten is a dump, compared to Moscow's Gorky Park or Zaryadye. Unter der Linden, is a small side street compared to Tverskaya. The state of public infrastructure between Berlin and Moscow is Heaven and Earth.
Munich is very nice, but in the end entirely lacks the scope. It is much cleaner, much better kept, and with more architectural polish than Berlin - but is still just a town. Closer to Vienna than Moscow: rich, orderly, boring.
Frankfurt is not a city but just a consolidated business district. People only know about it because of the airport. Aesthetics - sh*t. Cultural life - sh*t. If you have a layover in Frankfurt, take 3-4 hours, look at the Römerberg and walk along the Mainufer - and you are done.
So while we work on our toilets, you can try to catch up on the last 800 years of European history and develop a proper city.
