The Writer's Cabin at the Old Rectory just south of Westport met all my needs. And the setting is tremendous. Roisin is a gracious hostess. Not sure this would work for couples. I travel alone the scale of the Cabin was perfect. It's right off of N56 but you won;t hear any traffic noise. Amenities include stove, microwave, fridge, pots pans and utensils.
And there's a radio for listening to RTE One. Westport's a few minutes north and Croagh Patrick is even closer. Wish I could have stayed longer.
