My wife and I stayed 3 nights and it was a great experience. We drove into Sydney from afar and Vivian was able to accommodate our earlier check in time for our trip. Vivian's parents greeted us on arrival and were present throughout our stay. They were very nice and helpful showing us the building's facilities and the apartment. Speaking Mandarin would be helpful, but they speak enough English. We didn't formally meet Vivian during our trip but she communicated very well through Airbnb and gave us helpful advise on the area.
The room had a large closet with hangers, dresser unit, and a desk. It was spacious enough for our 4 bags. The bed was very comfortable. The toilet and shower are as in the pictures. They have complementary wifi which was sufficient however there were some dead spots in the room. There were cups/plates/bowls and fridge space provided in the kitchen for use.

The location is walkable to many thing - The Star Casino, cafes, pubs, restaurants, grocery store, Darling Harbour, Fish Market, and dessert places. They walk to Haymarket took 20-25min. The unit was near the Anzac bridge and the fish market, however, it was quiet and traffic was not noticeable. The area felt safe at night to walk into for the two of us.
Overall it was a great stay at the place and I would recommend it to others looking to travel to Sydney
