From the flat you can walk to the City Business District, to the Botanical Gardes and the Opera House or to a beautiful swimming pool. This ist very convenient futhermore the train station (Kings Cross) is just three minutes away. This is realy a big plus!
On the photos the flat looks nicer than it actually is. A renovation would be nice. And for example a new table.
As someone already wrote: A Backpacker-hostel is just in the neighbourhood, in the evening it can be very noisy. And in the street there is always a lot of rubbish.
And conerning my hosts: I’ve never seen them in this four weeks I was in the appartment. Maybe it is not nessecary, so don’t expect this.
All in all: Sydney is a great destination, I enjoyed staying in this city!
