The apartment is very beautiful. Two bedrooms and two bathrooms. It is clean and provided with all you need, from kitchenware to shampoo and soap.
The area is residential, all the buildings are new and some are under construction. There is a supermarket in a sort of mall very close to the apartment, with also bar and restaurants (check the closing time at night if you plan to have a late dinner). The transportation to CBD, Circular quay etc is not far from the apartment and was efficient (30-40 mins by bus or train). If you arrive from the airport, it is only 5 minutes train + 15-18 min walk from the closest train station.
I am a light sleeper but I was able to sleep quite well, even if one side of the apartment faces a noisy road and there are construction sites all around thanks to good insonorization. The curtains are not perfectly covering the windows so the sunlight fills the room in the morning.
Hai is a nice guy; he was a bit late at the checkin but he offered us to checkout 2 hours later to compensate.
All in all I recommend staying at his place.
