Moving to Dublin - Apartments Question

Hello redditors! I am moving to Dublin in about two weeks time and am having difficulty finding apartments. I have never been to Ireland, so hoping to get some pointers.

So far I have been in communication with New Market Yards which is appealing but also costs a ton. I can make it work but wanted to see if anyone had any experience with/recommendations for realtors or similar apartments near the city center.

Any advice would be greatly appreciated!
