We enjoyed our stay at Centennial Park. The apartment is cozy and comfortable and very well located, just a few stops from the CBD, close to Bondi Junction, not far from Bondi beach, etc. Our first time in Sydney and I think we chose the defect home base!
Being on the top floor of the building we had a great view.
it was a bit cold but a small electric heater helped keeping our feet warm.
The only negative point was that the Internet connectivity wasn't great, a bit too slow and often not going through. But that was fairly minor and we enjoyed being there anyway!
