Petra's flat is an easy and comfortable place where to stay. A direct bus connects the flat from Sydney international airport (bus number 400). You can walk to the beach (Bronte beach) and arrive there in around 15-17 minutes. The university ( UNSW) is close to the flat and you can take a direct bus to reach the main buildings. I often walked to Bondi Junction, where there are buses-trains and many stores. Petra is helpful and very nice so you can easily feel at home.
