In a few weeks I will be traveling to Eastern Europe and I need some assistance. I am trying to get a list together of hostels that are known for being really wild. Mainly hostels that there are always loud people up partying, no curfews, etc. The price and the quality of the room is of little importance. My tentative itinerary is as follows:

Zagreb
Sarajevo
Belgrade
Bratislava
Budapest
Prague

Any help would be greatly appreciated.

try the arena hostel in prague ;)
