Biel is a nice little city situated on a lake, but the fastest
connection is 1 hour 11 minutes. You can check this
out on
www.sbb.ch. You can even add your exact
address, and you can get a door-to-door time. Additionally,
the cost of commuting will be about 220 CHF per month.
Zürich is 350,000, but there are many nice villages
20 minutes outside of Zürich.
Thalwil, Horgen, Dubendorf, Adliswil are all about 20 minutes
to Zürich, and there are very strong expat communities although
not French speaking.
Cheers,
