We stayed in an 8bed dorm with a shared bathroom.
Getting there: Cost 24czk by tram (get off at the stop by a small football stadium) or about a 20min walk from the main train station.
300czk by taxi from a club on the river - 5stories
The room was very spacious with some lockers if you wanted to store away some small items.
There was supposed to be wifi available but all the people I spoke to had issues connecting, there were computers available if you wanted instead (quite a few cafes/restaurants had wifi so wasn't an issue)
It was a bit run down versus some other hostels I've stayed at and although the restaurants might have been a bit cheaper out this way the extra time spent getting in and out of town I would probably pay a bit more and stay right in the old town as you can find places to eat in the old town which are still very reasonable.
