The location of this spot is perfect. It's walking distance to the central areas, but you can also take several different buses. The bus stop is right outside or across the street (depending on the direction you are traveling). Adult fare is 2 euro, or you can buy a Leap Card down the street at the Mater Hospital gift shop. As other guests mentioned, there was traffic noise, but with ear plugs it was no problem for us. We really appreciated the early check-in, since we were quite tired. Great experience in Dublin!
