If you're moving for a job with Novartis or Roche, they should be providing you with relocation services. This typically includes three months of temporary housing. Homegate or comparis dot ch are good sites to look. You can plug it into Google translator for help. Again, but tram or bus you're never more than 15 mins away from anything. And if you embrace the biking culture here, even shorter time.

Feel free to PM me with any questions.

Good luck!
