'Lighthouse Unit' definitely preferable. However we have stayed in the Ground Floor Unit 'Sealion' which is still fantastic. Outstanding Ocean and Coast views. We found copious numbers of Mussels (only took legal 25 p/p ) on the rocks nearby.
Either lie in Bed or sit on the Lounge Suite and absorb the sensational views.
If you wish you can be self-sufficient as they have Stoves to cook on. Pauline & her husband were great hosts.
Absolutely love the place, as it hasn't changed and offers a 'way from it all' philosophy.
