Sue and Gary are exceptionally lovely hosts, very friendly and helpful. The apartment is really nice and tidy. It is beautifully designed and comfortable. A separate bathroom is a big advantage. It's really close to the city centre, Darling Harbour and the Opera house.
Also, as it was our first time in Australia, they helped us to figure out the most popular places to visit around and recommended a few things to do.
We definitely recommend staying with Sue and Gary, and we will be back in case we visit Sydney once again.
