Visited for a Six Nations rugby weekend. Hotel has the best possible location. The airport transfer bus stops right outside the front door (in both directions) and O'Connell Street is just around the corner.
It's an easy walk down to Temple Bar for food, drink and entertainment, and also to Grafton Street for shopping. Aviva Stadium is about an hour's walk (could have probably done it a bit faster) but there are buses and taxis if you don't want to walk it.
Excellent breakfast buffet.
Only slight gripe was that the room was very small but this wasn't a problem for us as we were not in the room very much.
