The description was accurate. It's a nice (big) bungalow near Glenbeigh village right next to Ring of Kerry. My wife and I stayed there for 3 days during our trip to Kerry. Unfortunately we couldn't meet Mary but she made sure that we didn't have any trouble getting into the house. There was a detailed how-to manual that helped us get acclimated to everything in the house.
Internet signal wasn't great, but that was expected considering the location.
Overall we had a very good time.
