Nice location, in the main road of the city, not far from the Castle and Medieval Mile.
Despite being upstairs a pub, the room isn't too noisy. The sound of the traffic light outside is not as loud as other comments said.
Nice bathroom and good water pressure in the shower. Only con: we left the window open and a spider came in to say "Hello". Since I am arachnophobic, that wasn't the best moment of the day. But... that's life (too).
Don't expect any luxury, but a well located small room where you can sleep. The rest of the time, you'll be busy discovering Kilkenny, so no prob.
(Sorry for my awful English).
