Gus is a Southbank apartment specialist, so he was my first choice when I decided to sell my Southbank property. His attention to detail was meticulous. He worked with exceptional photographers and printers to deliver a marketing package second to none. He was clear with potential buyers of what my price range was and limited inspections accordingly. In all, it was a fast and pleasant process. I would certainly recommend Gus as a trusted, knowledgeable real estate agent in the city.

Gus is a true professional to deal with. His knowledge of the Melbourne market enabled him to correctly market and promote my property and achieve the best possible price for my apartment, during a challenging time in Victoria.
