I had a very good stay in the apartment. It's very well located, in the middle of South Yarra and only a few steps from the train station -- close enough that you can hear the trains, but you get used to it after a couple of days.
The apartment is comfortable and well equipped, with a good kitchen and washing machine. There are a couple of things that could be improved, including cleaning a big stain on the rug in the lounge.
Overall, a very comfortable stay in a nice part of Melbourne.
