Elaine's place is a good budget choice -- near a fun area in Dublin, and fairly close by foot to one of the major train hubs. However, if you have the ill fortune of staying during a heat wave (as we did), be prepared to have the windows open to a fairly noisy street (both late at night and early in the morning traffic)... So, make sure you bring earplugs... and a circulating fan wouldn't hurt, too.
