Marlon was sooo nice and patient! He even drove me around the area when I first got there so I would have my bearings. He helped me with taxis and bus schedules -which I was making much more difficult.
Tip-the buses are much easier to navigate than I was making. There are a number of Bus 15s running often. Plus you can just google buses between Clongriffin and Dublin. It’s about a 15 min ride without traffic; double in busy times.
