Asunto: Accomodation in Czech Republic

Good afternoon!
I'm a student. In the end of July I'd like to visit Czech Republic. But all hotels are very expensive for me as a student. Can anybody help me with a place to live in or with an information about very cheap hostels?

Dimitri, Moscow.

Maybye i can...

Under what terms?

what place would you like to see? You know Czech republic is not so big as Russia is, but still its really important to know where would you like to go? Prague? The Giant Mountains?.....

I found a tour to Prague. It starts on 28 of July. But I want to visit other cities in your magnificent country. Can anybody help me as a guide there?) Karlovy Vary, Plzen, Brno, Pardubice or somewhere like that.
