We broke our AirB&B with this place and we were massively impressed. We booked and paid for the apartment more than 9 months ago and the communication started immediately from the host, Di [Dee].
The best way to get to Di's apartment from Sydney airport is by the train, getting off at the Museum station. You can use your credit card to get through the barriers, v as you would on the underground. His apartment is about a 1 minute walk from the station.
The apartment is lovely and spacious, comfortable living room with TV, xbox, sofas. A big double bed that 2 children can easily share, a laundry room, kitchen with coffee maker, fridge and everything you'd expect to find on your own kitchen. The bathroom is a good size and very clean with an excellent shower! Then there's the adult bedroom with another TV, double bed and wardrobe and drawer space.
Di was there to meet us, gave us keys and a map and told us where to go for best views, to eat, shop, etc. He was there to help with any questions should we have them throughout the stay.
The apartment is literally a 4-5 minute walk (maximum) from George St. This is the busiest Street worth all the shops you can wish for. Pitt St is also nearby and has a Korea Town with restaurants on it. This street leads up to a massive 5 storey Westfield centre at the top where you can shop even more!
A hop on to the train at the Museum Station and in 2 stops your at Circular Quay, where you'll find the ferries for the zoo, Manley Island, etc, the Sydney Harbour Bridge and Opera House. We walked through the beautiful Hyde Park and then the Botanical Gardens, this was a far better way to see the gorgeous green sites beside the concrete and steel city.
I believe we were spoiled with this apartment, but don't take my word for it, book or and see Sydney for yourself!
