The sad thing about Germany is their loathe for the English language: you basically cannot expect to fully live there without learning German. ATMs and self-dispensers (example: bus/subway ticket machines) are poorly translated to English, for example.

For example, bus/subway stops are only announced in German, not in English.

In Milan, Italy, bus and subway stops are announced in both Italian and English, public transport works very well in my opinion.

It's a pity that doing business in Italy is basically a rat race, taxation is ridiculously high (compared to the services and services level you get) and there is a crazy bureaucracy, otherwise Milan would be an awesome place for a tech hub.
