We usually hear that it’s London or Zurich due to high salaries being available there, but the high cost of living might take away a good part of it.
In your experience, which is the best city? Feel free to give your own criteria, be it the weather, culture, ability to navigate in English, etc.
Rotterdam or The Hague are a lot nicer than Amsterdam if you’re coming this way, and a damn sight cheaper, although housing is tough all over.
