Howdy!

I'm from the Bay Area, too, and I really miss Craigslist! Unfortunately, I don't have time to hang out, since we've got 2 small children to keep us busy, but if you have any questions that you think might require a San Fran perspective, I'll try to provide one. We moved to the area almost 2 years ago, and I feel like I know my way around now, but my French is still horrible, so I can't help much with that. Please let me know if I can help in some small way.

Thanks so much Szilvia! 

Did you try meetup.com?

and to find stuff, try petiteannonces.ch or anibis.ch or facebook marketplace

There's a weekly FR speaking group that meets in Nyon, no?  Here on glocals?  Might be worth to check that out, meet a few people etc.. Before jumping straight to a class room course? https://www.glocals.com/things-to-do/geneva/106337.htm

Rolle is nice, Nyon is full of EN speakers. 

Good luck!
