Dublin is the classic European large city. It's nice, but the real experience is outside the city. The cliffs of Moher, Northern Ireland etc contain the real beauty of the Emerald Isle.
The Hilton is a little "70's" looking. It is clean and the service was good. But everything looked dated. Not dated in a charming way...but more like dated in a John Travolta Saturday Night Fever kind of way. I mean, I kept expecting to see one of the Bee Gees walking by in a powder blue liesure suit.
But, again, IT WAS CLEAN. That's the number one thing we look for in a hotel. Just don't expect the extras and the quaintness that other hotels might provide. Food was very good.
