We stayed for a week in April. Very well equipped and very thoughtful interior design. We needed the heating on at times and had no issues. There is an electric BBQ outside too. Good technology, decent WI-FI, Sonos, Smart TVs etc.
In terms of location it’s about a 10 minute drive to Dunsborough (decent sized Cole’s supermarket and Bottle shop) and less to the start of Caves road and the drive to the wineries etc. The location itself is reasonably remote, there are neighbours but not too close by. There are a lot of wild kangaroos in the area and they congregate on the property at dawn and dusk. The children loved seeing them, the only downside is the large quantities of kangaroos scat everywhere on the property grounds which sort of renders any exploring to a minimum. This didn’t really bother us in the end. Also given the location the star gazing was top notch!
