Hotel advice for traveling Sydney - Rydges Hotel

This is the hotel I stayed for a week in Sydney. This hotel is right in front of the International airport(Literally in front of the airport terminal). Also, this hotel has reasonable price(about 130 Australian dollars). Very clean and easy to go to airport and subway station(which is in the international airport).

By the way, I rented a Toyota Corolla and that was the worst decision for me to travel Sydney. Especially if you are from culture of left driving seat, it was such a horror to drive in Sydney. And unlike my expectation, the transportation system in Sydney was magnificent. You can even take train to go to Blue Mountain and you can go anywhere in Sydney with subway. So my advice of traveling Sydney is "Never rent a car to travel in Sydney"
