Highly recommend Cahernane House Hotel if you're going to Killarney. We stayed in the carriage house in a ground floor room looking out onto the lovely courtyard, fields, and mountains in the distance. Breathtaking. Our room itself in its furniture, layout and decor was the perfect combination of simple/modern, and old-fashioned/luxurious - with a very comfortable king-sized bed, and a spacious bathroom with separate shower and large bathtub - and small touches like antifog mirror. The staff were very friendly, helpful and professional, and the breakfasts were tasty. We borrowed bikes one evening and biked around Killarney National Park, which was great. My only very minor complaint is the hotel could use to get some better bicycles, but I suppose it's tricky because if the bikes are too nice, they might disappear...
