My partner and I had a fantastic stay with Geoffrey, who was extremely accommodating and full of local tips. The apartment has everything you would need including air-conditioning for the summer and a beautiful log fire for the winter. The property backs onto a beautiful clearing, surrounded by trees filled with wildlife (Koalas, Cockatoos, Magpies etc.) with Kangaroos and Wallabies regularly bouncing through the property.
As other guests have suggested, make sure you bring all of your food (a BBQ is available), as the closest town is Apollo Bay (30 mins away).
For those heading down to the lighthouse, there is an entry fee.
The walk to Rainbow Falls from Geoffrey's is fantastic, so worth asking how to get there..
Very comfortable bed and pillows.
No mobile reception, so bring a book.. but there is excellent TV reception, so we didn't miss any Australian Open Tennis! :)
Would definitely have no hesitation in recommending for someone looking to get off the beaten track and having a connector into the Otways.
