I booked Ivan's place on behalf of my parents in law who were visiting us in Sydney, we live just nearby so can personally recommend the area as a great place to stay, so close to everything in town and with great transport links.
They really enjoyed their stay, especially the views from the apartment. The apartment had everything they needed.
Communication with Ivan was great (although we didn't actually meet as he was away), and he even left wine and chocolate which was a lovely touch :-)
