After quite a hiccup trying to locate the keys (very well hidden in the undergrowth, and more than one identical keysafe found), I finally found my way into David's apartment.
It's a really nice and comfortable place, quiet (except for the loud bathroom fan which only turns off if you shut off the main power) and the bed is excellent. The kitchen has everything you need and there is a great balcony with a fabulous city view. I didn't meet David (it's rare to meet AirBnB hosts in Australia, seems to be more of a European thing to get a personal welcome) but communication was ok.
The toilet seat was broken when I arrived - would have been good to have been informed of these little issues before I got there - and the bathroom wasn't super clean (other people's hair on the floor) but the rest of the apartment was great. Recommended.
