We stayed at Emma's apartment for 3 nights while visiting Melbourne and it was a great base - centrally located, stylish apartment. Emma was easy to communicate with; check in was easy (key was in a locked key box); and the Myki cards for use during our stay were a thoughtful touch.
One small point: the building's central fan/heating vent in the room is a bit loud at night and can't be turned off. But it is not too loud to sleep with and the apartment was otherwise very quiet.
We would highly recommend as a base for a few nights in Melbourne.
