The listing was exactly as described. I stupidly assumed that since it was over a pub I'd be hearing traditional Irish music instead of american pop. But the minute the pub closed the music stopped and there wasn't noise from people in the street after. I was there on weekdays, I'm told it might be a little louder later on weekend nights.
It was the ideal location for exploring Galway, easy to get to and from places by foot or bus. The shower room was a wonderful little surprise, I enjoyed sipping my coffee there from the balcony.
