We booked Chen Fei's place for 7 nights. Extremely convenient location with Coles, Woolworths, Kmart, Target, Myer etc etc in a major shopping mall (Westfield Carousel) directly opposite. There is even an Asian supermarket down the road for those who cook. It is very convenient as there is a very big food court opposite. On the top floor of the shopping mall are restaurants if you are too lazy to go to Northbridge. We tried a few restaurants there and they are quite good.
We rented a car (Burswood Car rental is a good choice as you can pick up your car directly from the airport even after office hours and their service is excellent) and there is a very secure parking lot at the basement. It is easy to get everywhere from Cannington. Less than half hour to Frementle, Swan Valley, CBD and only 10 minutes to Perth Airport.
Chen Fei is a great host and responds immediately to all messages. Overall a great stay. Her place is highly recommended
