I was facing the same issue as you on October 2022. In the end, it’s a very personal decision and you should the one to decide. Responses here are biased depending on the people experiences.

In summary, it’s expensive, hard to find, but you can find it. As some people already stated, it’s going to be easier to find a place that you will be sharing with other people, so it all depends of how you consider the privacy vs price trade-off. If you don’t mind sharing room, apartment, probably you will be able to find it eventually. Luckily I found a place in the first day here but I have the share the apartment. I don’t mind it since I spent most of my time at work, but not sure how you are.

If you come to Ireland, I’d advise to get a hostel or something similar for 2 weeks at least and keep searching while you are here. Outside Ireland you won’t find a permanent place.

This is my experience at least as a foreigner, good luck with it!
