I had a good stay here! My room was spotless and located close to social areas of Kilkenny. Chatter/noise from outside does filter in, but I had no issues while sleeping. Wifi was also extremely spotty in my room, but it connected enough that I could review my itinerary for the next day and sleep.
FYI for anyone hoping to drop their bag off early, the pub does not open until 3PM most days and Eamonn likely will not be there to help you in. If you're planning to arrive early and want to visit Kilkenny castle, there is complimentary storage with the ticket in which you could do before official check in.
