Very nice host, good apartment. Plenty of space, good facilitites. The apartment is situated in the ground floor so the main room has no windows except the sliding entry door and it tends to be a bit chilly - the stove is great, though. The bedrooms are great, same is the small bathroom.
Good recommendation if you want to stay near the city of Killarney. Traffic is bad there, but a relaxed walk to the center would take you half an hour.
