Dympna's place is outstanding and very close to the Cliffs of Moher and Doolin (<5 min drive each). You could even hike the ciffs from their place if you are willing to go on a long hike.
Everything about their apartment is top-notch. You will not regret staying with them especially considering the stunning view of the Aran Islands right out your window. We can't recommend this place and these hosts enough.
