I missed that it’s just for one semester as opposed to a full academic year. France makes more sense that way - easier to stick it out if there are aspects about the experience that really chafe.
I believe that, in order to cope with any difficulties that may come up, it is very important to choose to go abroad for the right reasons - because you want to be, specifically, there, not for the “experience” or the CV or because it’s cheaper or whatever.
Hope she has an excellent time. Bertillon’s ice cream on ile st Louis can make up for a lot!
