My husband and I had a very nice stay at Mark's place in St. Kilda. Mark was an amazing host and made sure we had snacks, since we arrived late at night for our check-in. Although we didn't need anything, Mark made sure we could access him by his personal phone.
We liked that the check-in was easy, just needed to unlock/lock the lockbox for our check-in/check-out.
The studio is well located and there are many restaurants and places to go nearby. Also, you'll have an easy access to Melbourne CBD by tram.
