Sure, here's my own personal opinion about some of them :

-Probably the most spectacular nature in Europe

Romania IS a beautiful country (in a old fashion kind of way) but i really double it that anyone who traveled around Europe a bit would say it has "most spectacular nature". Dunno, go to Faroe Island (as a example) and tell me afterwards how "most spectacular" is Transylvania.

-The largest number of tech specialists in the EU

That is actually the most misleading part though. Not sure if RO has the largest number or not but a potential investor should be aware that most tech specialist are actually located in Bucharest not Transylvania. And the gap in salary requirements/ skills between the 2 is actually pretty big (Bucharest >>> Transylvania). Heck until a few years ago Bucharest was the only IT "hub" in RO.

-Excellent private healthcare system

Yes and no. If you have a serious health problem , you'll get "shipped" to a state hospital and those are bad.

-Some of the greatest festivals in Europe

Guess it also depends on music genres. I'm into metal , for instance, and the metal festivals in RO are definitely not "greatest". It's not like we have Wacken here.

I fell in love with Romania mainly because of the people. You won't find other people being so grateful just because you say hi. Next, the nature: sure, Ko Samui is heavenly, but I'm more into `vampiric` landscapes. We opted for private healthcare(look into "Queen Mary" - this is what you'd choose). I don't know about public healthcare and I don't really care :-) There are two big festivals somewhere near us: Untold and Electric Castle. I'm a metalhead too, but Armin van Buuren, Tiesto or Faithless really sound good! Regarding the number of IT specialists, just read the reports. It's a fact that they have lower salary expectations, but they're hard workers who eventually end up in the US. This is why the author of the website is calling for entrepreneurs.
