Killarney is the perfect place to start the trip on the Ring of Kerry or to the Dingle peninsula and William was very helpful and prepared in this regards. He gave us nice tips about the trip, about what to do in Killarney, about where to eat and where to go.
The house itself is gorgeous, very big and clean, surrounded by a big green area. You can enjoy a tea in the garden if the weather is nice, which we were lucky to have. It's within walkable distance from the center.
I would definitely recommend staying at Williams place.
