The grand apartment on Macquarie Street features five bedrooms, four bathrooms, separate living areas and a study.
The heritage-listed Astor was built in 1923 and was the first high-rise residential building in Australia.
Flooded with natural light, the expansive apartment is decorated with contemporary furnishings, décor and an eclectic collection of art.
A white spiral staircase divides the living and dining areas, introducing an element of modern drama to the timeless space.
