I highly, highly recommend Fisherman's Cottage. It was sizable, clean, and close to everything - basically in the center of town.
Self check-in was super easy, as was parking. I lucked out and parked right in front of the house. However, if you're unable to grab a spot there, there's parking available behind the house. The house has a back door you can enter from there.
I had some issues locking the front and bedroom doors, but Barry was incredibly prompt with his responses and had everything solved ASAP.
Again, I recommend Fisherman's Cottage for anyone visiting Dingle. It's the perfect AirBnB.
