i havent stayed there myself but a friend of mine did and said it was lovely, you might find some reviews on trip advisor. with regards to getting into town there is no bus stop near by. you would have a bit of a walk to one, either outside liffey valley shopping centre which is about a 10/15min walk or you can cross the n4 which is about the same walk. you could get a taxi whixh woul prob cost bout €25, thats just a guess though!!!
forgot to add that travel from there into town by bus or taxi should take bout 30mins.....traffic does be bad at weekends and then there is the roadworks going on around the n4/m50
