It was a great experience with L'abode Accommodation at Woolloomooloo. Apartment was exactly same as described. Frequent 311 buses from nearby stop to city and famous site seeing locations. Woolworths and Coles are nearby. We tried Harris farm as well, they have almost everything under one roof required for family needs(could be pricey, depends on what you pick).
Mercury point is also at walking distance (~1 km). Thanks to Team L'abode.
