I don't see Romania as northern Europe because it is located further south than Paris. Bucharest's climate is more similar to Chicago. Montana is much drier and much colder. I would consider it Eastern Europe or Southeastern Europe. It has a climate more similar to northern Europe than southern Europe. However, by latitude, I can't say it's part of northern Europe. Bucharest is located further south than Venice. The northernmost part of Romania is on the same latitude as far southern Germany.
