I met Mary & John a couple of years ago. They are wonderful hosts. Although I have not stayed there, they showed me all around. I recommend the B&B in my "Quick Picks".
Whispering Pines is on the way out of Kenmare driving toward the bridge on the right. It is walking distance to town. It is a rather old-fashioned B&B, not purpose built. So the upstairs bedrooms have extremely tiny bathrooms that were slotted into closets. There is a room downstairs with a larger bathroom. But it was neat as a pin and has fantastic hosts. You will not get a finer Irish welcome.
