Pretty perfect for what you are going to want. I'll seriously recommend this place to people in the future although I was only in Shannon for ~16 hours. Beautiful location, great place, and probably one of the best places to stay to experience the general area (cliffs, Doolin, beach area, etc).
The house itself is pretty flawless for any airbnb purposes. When I was in a rush I couldn't figure out how to lock the door (more on my end probably, I only tried for a second), but it felt so secluded and safe that I didn't care to anyway.
Plus John was very accomodating and his dog we ran into (Jay Jay?) is super cute
