Hi! Living in France, everyone, and I mean everyone, has heard of Université Pierre et Marie Curie. It has ridiculously high entrance requirements, something like 18/20 and above, and you may (I can't remember) have to pass the concours, even if you're foreign. I would imagine that it's the same or Université Bordeaux 1. Just be aware that if you fail the concours twice, you can never pass it again. During your degree, you will probably pass more concours, and the same goes for those. A concours is basically an exam that they use to thin out the numbers. A French degree is highly competitive. (Just an example, the Ecole Nationale de Météorolgie has about 5 places for 200 applicants)
Secondly, Paris is probably the most expensive place in France you could choose to study in. It's an amazing city, but expensive. I don't live in Paris, so I wouldn't be able to tell you much about it. You would need to speak at least a bare minimum of French as well.
I don't want to put you off of going though!
If you want to talk more about this, then you could PM me if you like.
