We had a wonderfully unique stay at Peter's place at the birds nest. Peter is a friendly host. It was in a magical location, perched over the sea with crashing waves from the window and a private beach. The shower was nice and warm (albeit completely outside, so a dip in the sea is recommended before the shower to acclimate). The amenities are basic but we didn't mind at all. It would probably be a good idea to have a good shower and prepared food+snack for your stay. If not, Dingle is about 25min drive away.
All in all, we thoroughly enjoyed our stay. A really unique experience and a must when travelling in Kerry.
