I had a really good stay at Colleen's "oasis in the city" . She made me feel really welcome and gave me a lot of useful information about what to do in Sydney and how to get there. Her place is in walking distance of museums and other touristic attractions. It is also close to the bus stop and the train station. I would definitely recommend to stay at Colleen's if you're spending a few days in the city and love to walk around.
