Great cabin in a beautiful little spot. Kathryn was a great host to deal with. The cabin is much more spacious than it looks in the photos and has a unique and interesting design. A bit tricky to find if you arrive late at night like we did so be sure to download Kathryn's instructions so you can access offline if you don't have reception. There was no Vodafone/Kogan reception there but Telstra worked.
Highly recommend a stay here. Waroona is also a really cool little town to explore - we were pleasantly surprised at its character and charm :-)
