Hi,
We stayed at the cabin in Simpsons bay in December 2019 as we were in Tasmani visiting our son our xmas and the New year. It is in a stunning place by the coast and has fantastic views and was so quiet and peaceful.
And the only little niggle was that there were no bug screens for the patio doors so we had to keep them closed.
So having said all that the Q is "would I stay again"?. Definately. The position is amazing, the cabin is comfy and well equiped (no wifi so we brought our own though), your own wallabies in the garden (amazing for us Brits from London :-)) and completely isolated - what more could you ask for?
