Totally, people from Romania are the same that people from Netherlands. Only minor differences like history, culture, language, life expectancy, religion, etc. are different. :)

Btw. I did not say that all 13 nationals are from Europe, in fact they are from: India, Pakistan, Algeria, South Africa, Australia and United States. They did not have a rough time to come to Munich and they love it here, have kids, speak German and integrated into the society more than I am (I am from Europe). I am not sure how they managed to dodge the racist Bavarians.
