Hilton Dublin Airport for Gold
Just adding to the post for future reference: stayed here over the 4th of July--Gold
Stayed here for one night before a flight back to US in a family room--greeted by name with fruit, water and chocolates in the room and beds turned down (queen bed plus 2 twin sofas pulled out for the girls--reported they were comfortable). Free wifi with no connection problems. Free, full Irish breakfast before the long flight was particularly nice (and our last Irish breakfast after a wonderful vacation!). It's about a 10 min drive or so from the airport--we had rental so didn't use shuttle.
