We stayed at Guy's house in Yallingup for 5 nights in January and had the most amazing time. The house is large enough for 2 families (4 x adults, 5 kids) to live together, eat together and play together, with enough different spaces and seating arrangements to enjoy personal space. The grounds are huge and very peaceful, with kangaroos visiting early in the morning (such a bonus for the tourists to see!).
Well presented, clean and very well stocked with crockery (including plastics for younger kids), glasses and kitchen equipment. An outside undercover BBQ area was great for communal breakfasts, lunch and dinners. A number of board games were available to use, and a selection of wines to purchase if you haven't brought your own. Location is great, just off Caves road, half an hour drive to Margaret River town centre and 20 minutes drive to Dunsborough (Coles supermarket). Lots of vineyards nearby.
Guy was welcoming and quick to answer questions. I would highly recommend this property and would definitely consider staying here again.
