Try the stayokay hostels, the one we stayed in was sweet as, 4 in our room, no hassle, pool table and bar downstairs, away from the aggro in town too.
If you would prefer the aggro, stay at Durty Nellys, right on the red light, minutes away from all the good stuff.
Enjoy the place for what it is too, as said above boozy groups of blokes aren't that common there (most of the beer hounds get too battered in the coffee shops too early in the day), don't skip something thinking it'll be seeds or not your seen, do it while you're there and enjoy it man. The first time I went, I ended up going three times the same year, it blew my mind man, and some of the women, not just the tarts, christ mate SMOKING HOT.
But, always check your change there, sometimes the bars will short-change you
