Really great hostel. As for getting there: bus 8 and 31 go there from the main bus station, number 12 does not (anymore).
Nice place, clean showers (a bit small unfortunately), nice pub downstairs. Metro station is really close and it's well connected to the city centre. The only negative point was that for me the wifi did unfortunately not work - this was an account problem rather than the hostels fault because other guests I talked to had no troubles.
