Very basic but comfortable place to stay. The pub is close to both the black abbey and the "down town" of Kilkenny city.
The only time I remember hearing significant noise from the bar in my room was when there was a band playing, and even that wasn't bad. Occasionally had to close the window to block out sidewalk noise, though. My room had a sink, which was handy. The room and shared bathroom were clean, and towels were provided.
Definitely feels like the upstairs of an Irish pub: tall folks will need to duck a few times, stairs are very uneven but don't seem unstable.
