If you're coming from the airport, take the 747 bus to Usher Quay. Walk back (against traffic) a block to St Augustine St. Walk up a half block until you see a large iron gate on your left with City Gate written over the gate. You will need a code to enter the gate and another one to enter the stairwell. Number 98 is up one flight of stairs. The room is small, but clean. You're on your own to find a place for breakfast. Dublin's oldest pub is just around the corner for a nice dinner. We used the green "Do Dublin" hop on Hop off bus to see the sites. Stop 30 on the route is just across the river. When leaving, cross the bridge and go left to get the 747 back to the airport.
