* Alternatively there are some active members of [http://www.hospitalityclub.org Hospitality Club] or [http://www.couchsurfing.com Couch Surfing] who are willing to share a place to stay and an advise with you.
* You can also try to stay in students dormitories. You just need to find someone who will let you into the dorm. If a student wants to host someone he is obliged to pay some 6 or 8 PLN (EUR 1,5 .50 - 2 €), but you may have a chance to sneak in for free.
* The cheapest hotel in town is situated just next to the dorms. The double used to cost 80 PLN. I'll try to confirm the price soon.
