We found Ardree House to be a great place to stay in Killarney. The room was comfortable, spacious, and impeccably clean. The staff were friendly and efficient. It's located only a 5-minute walk from the centre of town. It's on a somewhat busy street, but the house is set back from the road a bit, and we found the room to be very quiet (though ours was in the back of the house). The breakfasts were very good. Overall, very good value for money. We would stay here again if and when we return to Killarney.
