Upon looking further, my comments were meant for Morrison as that was the subject of this thread, so please do not use these directions for Burlington DT. Sorry.

Taking the Skylink 6 euros single, you get off at O'Connell Street right next to the Spire. You can walk towards the river and then take a right and walk along the river for several blocks. Maybe 10-12 minute walk. Depends how many bags you have and how fast you walk. You are making a right angle that way, however. After getting more comfortable with the neighborhood, cutting through Jervis shopping area is 3-4 minutes faster as you are walking the hypotenuse but upon arrival, I recommend you take sure route. Just when you think the trek is getting long, the hotel pops up. Hotel entrance is on side street.

LUAS stop on Jervis is 2 minute walk max out back of hotel. Very easy, ticket machines on curb.

Hotel is well located for walking to most places, however. The only time we took the LUAS was to get to Kilmanheim to rent our car on leaving Dublin.
