I found it on googling about Rental laws in Zurich/Switzerland. I had a tough 1 and half month searching for an apartment in Zurich. Being on temporary work permit, not many people entertained my applications. Finally I found one and my collegues started advising on a to-do, not-to-do list. Some of the points they mentioned scared me - so I figured I need to do some research on it, googled, and found this lovely forum...seriously, this is such a helpful forum, with loads of useful info !
