In relation to the French press saying Argentina is dangerous, I can honestly say that after a year and a half here, I have never felt unsafe.
I also want to point out, as a British girl who lived in the south of France for 4 years before coming here to BsAs, I felt unsafe all the time in Montpellier because of the constant aggression of the French Arabs who relentlessly chase women, and shout insults as well as have no qualms about grabbing them if they want! This happened to me in Montpellier twice as well as various scares I had in Nice! and it was also in city centre in day light! I would never recommend any woman to live in Montpellier if you want to go out on your own and walk safely. However, I would recommend to any women to live here!
So, as far as I'm concerned, if you are sensible about where you go and what you do and how you behave etc, you should be ok here, like in any city in the world!
