To answer you tax question, check my previous comment. As for performance indicators, I quote: "Romania will be an economic growth outperformer in Central and Eastern Europe (CEE) in 2016, and the second fastest growing EU economy (behind Ireland)."(http://www.bmiresearch.com/romania). Also low labor costs, ferm legislation.
This far, I've heard only good things from that area. From people who worked or studied there.
What I'd expect but didn't see: Is the tax-system competitive? How about the other performance indicators regarding incorporation, labor costs and legal certainty?
