Hi,
Just hoping that this will start a list of short-term rentals available in Zurich that people can refer to. It's a frequent question that almost everyone asks when moving to Zurich.
Also, if someone's tried something on the list, feedback is also good.
So here's my small start:
I think it's worth taking a look at student online ads:
http://www.students.ch/page_index.php (German/French)
http://www.marktplatz.ethz.ch/index.cgi (German but occasional sites in EN)
There's also company that runs short-term furnished apartments:

Saw this tucked away off Seefeldstrasse on my way to lunch:
