With the exception of super huge cities like Paris, London and Hamburg 2000 USD is enough for a very good life even in western Europe. I lived in a couple of places in Germany, smaller to mid size cities, with an average of around 800 EUR per month in a single room apartment alone plus food and other costs.

Sure 2k will buy you much more in the east than in west but one really must have the aptitude to live in a place that is very corrupt, psychically and morally dirty, depressing and everyone is super unhappy and always complaining. Wouldn't call that the good life.
