The location is perfect - not too close to downtown where it is noisy, it is on a smaller quiet street and a quick 5 minute walk to Grafton Street and the action.
It is down a narrow stone curved stairway. If you are older or have mobility issues it may prove challenging.
There are not many amenities. We ended up purchasing coffee, creamer etc.
The bathroom is functional but tiny, which is understandable given it is old Dublin.
