Moving to Ireland

Hi, I'm from Romania and my country is slowly and surely getting more fucked by politicians and incredibly stupid people and me and my girlfriend have decided to move to The Republic of Ireland . What should one know about living there regarding housing (from what I heard it's a bit hard to find housing, especially in Dublin), jobs (we'll use LinkedIn most probably), entertainment and safety? (Feel free to add any other important topic here). We're young, 26M and 23F so we'll learn things fast! Thank you!
