Catherine's place was great! Everything looks exactly like the pictures. The space was very comfortable for 2 people. An extra plus was that it has a washer and dryer.
The location is convenient. There is a Coles Supermarket close to the train station which is a 2-5 minute walk. Sydney opera house is a 30-40 minute walk. We never had to pay more than $12 AUD for an Uber if you want to go to the city center.
I would definitely recommend staying here is you are visiting Sydney.
