The apartment is in a great location in Kirribilli, within walking distance of the train that goes across the Harbour Bridge (15 min walk) and the ferry to Circular Quay (5 min walk) - or just walk across the bridge to the Rocks and CBD (30-40 min walk). The view from the apartment is of the bridge and Opera House and is stunning, especially if you go down the hill to the side and rear of the house to a little wharf. Kirribilli has lots of convenient shops and food places including an excellent Thai, Indian and sandwich shop.
The apartment itself is well equipped, comfortable and air-conditioned, with a decent kitchen, and a sizeable living room/dining area. Two bedrooms are downstairs - here's the only snag: downstairs is via an iron spiral staircase which is steep and narrow. If you are physically challenged, this may prove too much, and it's surprising how many times you'll need to do the 'journey'. Don't try to take big cases down those stairs - better to use the steps at the side of the house and go through the gate from the street; quite a few steps but so much easier than the spiral stairs.
One bathroom is downstairs with an excellent shower, toilet and small sink; the other is upstairs, with a washer/dryer (which takes forever to wash/dry, but is handy) and a decent shower, and toilet.
As the bedrooms are downstairs, one of them can get a little noisy due to the footsteps of the neighbours, but the beds were comfortable and the rooms were big enough. There's also a living room area downstairs with couch and TV.
All in all, a showcase accommodation; not cheap, but given the location, views and locale, definitely recommended, and Getawayz was great in communicating with us - entry codes, property info, etc.
We had a thoroughly enjoyable time in Sydney, enhanced by the property we stayed in.
