I have recently stayed at Harbourside Tranquility with my best friend (2 girls in mid 20's). I can strongly advise it to anyone looking to stay in Sydney.
Not only was the accommodation beautiful, clean and pretty but Andrew & Anne were such lovely people.
The accommodation is exactly as it looks, and my best friend and i were very comfortable. The bed is huge and there are plenty of facilities. The house is in a beautiful area walking distance to the ferry points which take you all around. It is a bit hilly but it is not an issue when you are at leisure. I highly recommend this accommodation.
Andrew gave me a tip on where to go running and helped us to the ferry with our bags on the last day.
Both Anne & Andrew were very understanding of our privacy too and gave us plenty of space.
Dont hesitate you book here for the price. What you see is what you get and you will have a lovely time.
