We stayed in the apartment for four weeks on our first visit to Australia. There were four of us but the apartment could accomodate 6 with without a problem.
The apartment is well located for visiting Melbourne Centre with most attractions being within walking distance. It is well equiped and close to shops, restaurants and pubs.
Communication with / from Debra was excellent and booking in / out was easy.
We certainly recommend the apartment if you want to be near the centre of Melbourne.
