Our group included a baby and a toddler and the only issue was that we wished we had booked for much longer. Bonus was being able to use the washing machine and the effort put in by Tom and Glynis to get our belongings up the hill and make sure we were comfortable. We enjoyed the nearby tumbledown bay, and doing the bush walks on their property.
It is very basic off grid accomodation with loads of little special touches to make it comfortable. Leave your phones off and bring some old comfortable clothes and several good books. Enjoy.
