I just went for a couple of days with my adult son and dog.
We all enjoyed the house. It was well set up and very comfortable. Beds were good. Everything clean and tidy. Well fenced off. Nice and quiet, and dark, at night.
It is in an amazing location. The beach water is about 50m from the front door. The beach opposite is incidentally a dog exercise beach which was ideal for us.
We enjoyed beach walks including walking to the White Elephant in Gnarabup for breakfast each morning.
I would (and already have) highly recommend this place to others.
