Had two layovers in Dublin recently, both were fairly smooth.
On the outbound, we stopped here between America and England. This was a really quick and easy process, as there were no lines and the passport checks were straight forward. No fumbling around with extra paperwork or questions. Security was fine as well. With the relationship that Ireland and the UK have, it's definitely easiest traveling in this direction.
There isn't an abundance of seating, so many people (including us), spent a fair amount of time standing around waiting. Our flights, and two other gates near by were all delayed - which I know is an airline issue, not an airport issue - but this seems to be a trend lately so be prepared. While you're waiting however, there is a good size food/shopping area upstairs (open limited hours). We wondered around there and grabbed a coffee and scone from a really nice vendor.
Bathrooms are clean, no complaints there. Very appreciative of the large, private family restrooms as well, which we used a few times with our 10 month old. Good size changing table area, sink, and stall all included in this space. Very well-kept.
On our second layover here, returning back to the US, it was definitely more hectic. If you're traveling to America, get ready to be shuffled downstairs in a big ol' long line through customs. Oddly enough we had to go through security a second time as well. Don't get me wrong, the process was pretty easy and quick considering, but definitely prepare for extra time ahead of your flight. Because our flight was delayed (again), we had to basically run after we made it through. Luckily for US citizens, like myself, the line is much shorter. Also so much less chaotic then going through customs when you land in the US... I preferred this for sure!
All in all, it's a clean, easy airport. Not much more you can really ask for.
