Probably a huge longshot but i was wondering if anyone in the kreuzberg area knows of somewhere cheap my friend and i could stay over the new year period?

We'll be flying out on the 28th december and returning around the 4th. We could probably manage 150 each for the week so if anyone is leaving berlin for the festive season and willing to rent to two very responsible youn ladies please get in touch!

Or if anyone can recommend reasonable hostels in the area that'd be a huge help also...

Many thanks
