Frankfurt (am main)

[threeheadedpuppy]

Okay, so I just found some flights to frankfurt for next to nothing!! But before I book them, I wanted to know if anyone had any good suggestions for cheap accomdation for a group of 8 people - we went to prague last year, and found a really cool apartment that had 3 single beds, two sofa beds and a 2 doubles, which fit us all in quite happily (apart from the two guys that had to share :S)
So is there anything similar in frankfurt? I can't find any!!! Help!!!

thx
