We spent a night at the RACV City Club, having been booked in by a friend (who is a member) to attend an evening function.
As non-members we paid $260 for a twin room, with valet parking and full buffet breakfast included. Our room was huge, with two very comfortable double beds, a separate dressing room, and a large, well-appointed bathroom. The decor is modern and stylish - the only disappointment was the outlook into a void between office buildings, although given the city centre location, this was to be expected.
We couldn't have been happier with our accommodation - for the price paid, it was excellent value, right in the heart of the city.
