Erika's room was a really nice place to stay for our weekend in Dublin.
The flat is quite big, in a charming residence, just outside of city center.
Everything worked perfectly (we couldnt make the electric heater in the room work but I think we just didnt do it the right way), we didn't have the chance to see Erika but her roomate was here to help if we needed something too.
Buses 13 and 40 have stops at the gate and go directly to the center in a few minutes.
Kilmainham Gaol is just 10 mins away by walk, same for Guiness Storehouse.
Don't hesitate any longer :)
