Absolutely fantastic location!! 10-15 minute walk to Darling Harbour, 20 minutes to Pitt St Mall and 35 minutes to Circular Quay. If walking isn't your thing you are only a 5 minutes walk to the light rail and 3 stops from central.
Communication with Annie was great and check in was a breeze. The apartment had everything we needed. There is a cafe next door and a IGA Express a few minutes walk away.
The complex is noisy as a result of the open layout interior and people coming and going. I would recommend that you take earbuds to sleep in if you're a light sleeper.
I would definitely stay again and I would recommend Annie's apartment to other travellers
