so, apartment is advertised on www

and you find it attractive enough to apply for it

and the agency (or whoever) finds you good enough to offer you the contract

and you see on the papers that the price is 100 or so chf higher then advertised on www


is that ok? somehow it doesn't seems but who am i to tell...

It is possible that the extra sfr100 could be for heating etc. Sometimes apartments are advertised with just the price of rent + nebenkosten. Maybe you should have the contract checked out.

no, the prices that i am talking about already include additional charges
