Frankly, all that's said in other reviews is true. The location is beautiful, the room is unique and (initially) romantic, it's close to the CBD and you'll likely see wallabies. However, there was one major issue that made our stay less enjoyable, the door is broken and is not secure. We stayed for two nights, and on the second day we returned from a day-trip to the outward swinging doors wide open to the outside world. Naturally, we thought we'd been robbed, or that we'd be greeted by a party of snakes or lizards inside. Neither was true, and we discovered the culprit was instead the wind when we were subsequently woken up at both 3am and 5am that night to the door catching the breeze and slamming open, frightening the hell out of us. The door was locked every time, but since it's broken it takes just a small breeze for the doors to split apart and open. The solution we had was tying the door handle to a piece of furniture which worked a treat but MacGyvering wasn't something I was pleased with doing at 5am on my getaway to the Magical Mountain Nest. This may not be a dealbreaker to some people, but I don't like my valuables being exposed. It may also appear harsh me whining about this in a public review, but I've chosen to because the problem is already known to the host but hasn't been fixed -- we were told there were issues with the door at check.
The other downside to this Airbnb is a personal opinion (and transparent in the listing itself), but the stone curved half-wall enclosing the open toilet and shower is simply unsavory after the initial novelty factor wears off. Neither of us enjoyed hearing, seeing or smelling the bathroom business just metres away from the doublebed in full HD. It's a room feature that looks great in photos, not so much when you have to use it.
