Four of us- two couples and a baby stayed in Robbie's apartment, the location was good with an easy 5/10 minute walk to the tram station.
It was comfortable and spacious- we loved access to the dishwasher and washing machine (note if you were someone with mobility problems the apartment is located up a flight of stairs.)
We didn't meet Robbie, but he was communicative and helpful via messages and all up we really enjoyed our time visiting Melbourne and recommend Robbie's apartment.
One thing that would have made our stay better is a second lounge, the apartment comfortably sleeps four but there's only space for two people to comfortably sit in the lounge room.
Thanks for the enjoyable visit :)
