Eamon's place was easy to find and parking was just behind the pub for €2/day.
Checking in was easy as we just went through the pub and were let up to our room.
I do agree that if you have a room that overlooks the Main Street it can be a bit noisy even with the windows closed— cars driving past and the sidewalk crossing beeps for a very long time and quite often in the evening.
If you're in Kilkenny for just one evening it is a fine place to stay, clean and comfortable.
