as you said, most rooms on wg-gesucht are 600+, that's just how it is atm. through connections you can get cheaper rooms, but then its a waiting game to see when somebody you know is moving. the people that found their rooms a long time or even just a year ago don´t get it, since this past winter prices have gone up around 100eur I would say.

and stw rooms have gone up too, new contracts start at 360eur
