I only stayed the one night - prior to an early morning flight from Dublin Airport. Hotel courtesy bus very efficient between terminal building and hotel (which is very close, but due to the extensive building works around the airport you really wouldn't want to walk!). Booked a single room (and was allocated a room with three single beds) - room fine, bathroom & toiletries very nice, everything appeared freshly painted, and most importantly: it was really quiet (despite the many guests).
Would really recommend this hotel - don't let the boring exterior put you off - it's a slick, modern hotel inside!
