How to find an apartment in Melbourne cbd to rent

Im planning to relocate shortly from regional vic and want a city apartment to rent but i dont know where to start. I cant attend inspections as i am too far away currently. How do i avoid buildings that are student accommodation? Im looking for something new never lived in or recently renovated. As a single female are there safer buildings than others? I need to be within walking distance of Southern Cross station. Any buildings that i should avoid?
