I don't know if this applies anymore, or even applies to Geneva, but the Swiss correspondent of the BBC once moaned at me that if, as a foreigner (not EU remember) you have a job in a town, you have to reside within the town. Which means for places like geneva that everything is expensive cos all the many foreigners have to live in the restricted zone. You're NOT allowed to live outside.

Now that could have changed, but it's worth checking cos that will make a huge difference to what you can afford. I suspect that studenty places like CERN etc get dispensations, but financial may be different.

However, good luck

keep to the Fen Causeway
