Go for it !
The house is great, it is really clean and spacious. The bathroom is private and the room lovely. There is a beautiful view on the hills all around the house, and it is very quiet.
The house is ~30min walk from Killarney, we rented bikes to make it in less that 10mins !
The breakfast was really good : awesome homemade scones, jam, butter, cereals, tea, coffee, yogurt, fruits, etc.
And most of all, the host was super nice, really welcoming and accomodating. She advised us on what to do in Killarney, and is eager to have a little chat with you if you want.
We really enjoy our stay there, 100% recommanded !
