Fred's place is lovely. He is very communicative and provided clear instructions. Admittedly we only stayed for a short period after arriving after 10pm and leaving at 3am to hike up Mt Amos for sunrise, so we didn't get to see the house in daylight which we would've liked to explore more around the area. If you are planning to hike around wineglass bay it may be worth staying a bit closer as there is no direct road from Dolphin Sands to Coles Bay which means you have to drive around despite the small body of water separating the two locations.
All together a great trip and will be back again!
