Slieve League House was one of our favorites on our 2-week trip to Ireland. It was clean (looked like new), warm (working radiator and hot shower), and genuinely friendly. We arrived late and without dinner, and Kenneth called the local pub before they stopped serving food to inform them we were coming. The lady helping with breakfast was also very kind. Their Irish breakfast included mushrooms and baked beans that made it extra delicious.
Highlight: This B&B must be the closest one to the Slieve League cliffs. We were pleasantly surprised the next morning at the short drive!
