I stayed with my husband, two kids (5 yo and 2 yo) and my parents who are both in their 70s. The house was really lovely and the location gives it a really beautiful view across Killcare/Putty Beach, which we really loved.
The house was clean and well equipped and the agents at Ray White were fine.
There are three suggestions I would make however, especially considering the high cost of the property.
There is no welcome manual - so you have to figure out how everything works which you don't really want to be doing as it feels like you're wasting time, especially if you are only there for a few days. Most holiday rentals/airbnbs I have stayed in have some sort of welcome/instruction folder which tells you how to switch everything on/get things working like the wifi/hot tub/heating etc... We figured these things out but it took us a bit of time. For example there is a wifi password on the walls but you have to guess which actual wifi you need to connect to as only the password is provided. Also the hot tub - there are no instructions and we had to work out through trial and error that the switch was hidden under the house. We couldn't actually use it either as it was filthy - perhaps needs a good clean out. When you are paying premium prices you expect these touches.
And lastly, and most importantly, the little pretty garden which goes beyond the pool really should have some sort of fence or at least a warning sign - because at the end of it is a sheer drop , which is partially hidden by small shrubs/plants. But if you were a young child and went running out of the house, passed the pool and onto the lawn and you didn't stop or you tripped, you would be over that drop in seconds. We were all gobsmacked that there is no warning of that in the house anywhere, or on the online ad. We had to make sure neither of our kids went down there during our stay which is a bit stressful. Strange that there is no fence at all - or like I say, at least a warning. So if you are travelling with kids, watch out for this.
All that said we enjoyed our stay overall, and if these few suggestions were actioned I think it would make it a really great holiday house worth every penny.
