I lived in Geneva from 26 to 28 years old, as mentioned in other replies, come back to Switzerland every time I manage to, and have several good Swiss friends.

I also had to help a friend of mine newly moved into Baden in 2018 to settle in, so I know what bureaucracy she had to face until she was 100% done with everything and could carry on with her life having a proper bank account, address, mobile phone, internet, new car registration, the whole package.
