I would recommend that you meet Julia in person when you arrive rather than relying upon the complex directives. This will avoid wasting time in getting into the flat, locating the car parking space (note that the car park numbers are not in order and you will have difficulty parking anything bigger than a Camry - even with the side mirrors turned in), and how to set the air-conditioning system. Note that these is a large fine ($500) if you loose the flat key.
If you have any substantial luggage, then I would recommend parking on the pavement outside the flat (the road is a no standing zone) to unload rather than the long walk from the parking spot to the flat - especially since the lift is out of order. Note, if you park in the wrong space, your car is likely to be towed away - at your expense.
The flat itself was spacious and quiet, although rather sparse in terms of utensils in the kitchen. Location for the Sydney Olympic Stadium was excellent. There is a Safeway Metro store in easy walking distance that does good coffee and take-away food as well as the usual supermarket stuff.
