there are a few hostels to be found around the main bus terminal i stayed at the bru bar and hostel on maccurtain street (i think?). in terms of things to do, there are plenty of good bars and pubs along st. patrick's street and with the art school nearby, prices shouldn't be too bad.
oh and avoid going to kiss the blarney stone, it's a rip off and the gypsies piss on it at night.
