I can't express how much I enjoyed my stay in the Black Valley. The place is really magical. It is rustic, and it takes a bit to get there, (I think you should get a medal for driving the Gap of Dunloe!!!) but once you're there, the worries and fast pace of this modern world just melt away. At night, the silence is amazing, and in my opinion, the house has just enough amenities to be comfortable but stay rustic, and still experience the way people lived in the past. I thoroughly enjoyed my stay there and will go back again as soon as I can. The only problem with the place is you won't be able to stop taking pictures!!! Everywhere you turn, there's a great picture. I absolutely loved this place!!!
Also, a tip I go from Scott. If you need things, I would go into Kenmare as opposed to Killarney. Great little town, with friendly folks. I think it's closer and the road is much easier to drive. The Gap of Dunloe is spectacular, but not for the feint of heart as a driving experience. I would strongly recommend a visit to this place!!!
