We booked Sharon's place for our stay around Margaret River region. For driving along the Caves Rd south to Augusta and up north to Dunsborough it is a perfect place to stay. You can easily reach all the beaches and the wineries are close by. We really enjoyed our days at this place. We loved the very comfy bed, the luxury bathroom and all the details in the apartment. The nespresso machine was a nice detail which finally brought me good coffee again ;-). We enjoyed our breakfast on the porch every morning.
Margaret River city is 3k away. We would recommend to use a car or bikes to get there. But to be honest you need a car anyway to get to Margs.
