Not the greatest..
We stayed on a Friday night, and were on the 7th floor. We could hear 'nightclub' thumping music from about 11pm, which we could hear over the sound of the television. I had to sleep in earplugs.
The decor is , in my opinion, dated and some of the furniture looks well worn (particularly the tracks in the carpet from years of tread) and scuffed and like something out of the 70s. Saying that however, it was clean and well tended. Just not my personal taste. 
Staff were all very polite and certainly no complaints there. I used the gym, which, considering the size of the hotel, was tiny with only a few old pieces of equipment. Any more than 6 people in there and it would have been very cramped ! And you have to walk through the Irish Bar to get to the gym, which I didn't find particularly pleasant.
