Andrew's place is the definition of the perfect AirBnb stay! I stayed there for 2 weeks when I first moved to Kilkenny and it litterally became home away from home.
Andrew will go out of his way to make you feel at home and comfortable. The location couldn't be any better: located just opposite the beautiful Kilkenny castle with amazing walks and adventure possibilities. It's literally a stone's throw away (1 min walk) from the city center and all the nice things Kilkenny has to offer (amazing restaurants, pubs, art, etc.)
The room is spacious and clean, the bed is amazing and the bathroom is bright and spacious too.
You should definetely stay there when you get a chance to visit the city.
