Long story short: My original place that I booked for my vacation was a noshow so as a last minute booking, I could not have been happier. It is above a shopping complex but you don't get the noise of the shoppers as you're 5 floors up. It is next to a main bus terminal and eventually on a rail line, so you won't be too far from town.
The hosts were super flexible and were always available, if needed. I know when I return to Sydney, I will be booking this place again.
