It's called a "beach shack" but definitely a much much nicer version of my idea of a shack! Super comfortable apartment with everything you will need for your stay.
Minutes away from the beach and the White Elephant cafe through the dunes (to go to the dog beach you need to keep walking a few more minutes north).
Great enclosed yard, both our dog and toddler loved it.
We met the owners and they were so lovely, they even let my daughter play with their grandson's toys!
Definitely stay here if you want to be in Gnarabup, we hope to book again for our next trip down south! The only thing I'd recommend bringing extra are black-out curtains (like the gro-blinds) if you have a baby that needs day naps, as the bedrooms get plenty of sun.
