We were two couples staying for a few nights at Moore River (Guilderton). Unfortunately, another couple weren't able to join us, but the property would have easily accommodated six.
The ocean views were gorgeous, the house roomy and comfortable and the kitchen cupboards had all the utensils etc we needed. Two bathrooms (one downstairs) were a welcome bonus.
Only one minor negative - BBQs rusty or dirty so we cooked in kitchen.
Highly recommended - we wish we owned this one!
