Where to stay in Frankfurt - cool and cheap?

Hi,

I will be going to Node 15,
And I have never been to Frankfurt,
was wondering if anyone has plans of renting a Vvvv Mansion :). Or if anyone knows of cool spots that I should look into.

It would be cool to be around fellow vvvv people, or just near the event site or near the down to earth night life section of frankfurt.

Let me know.

thanks
