My husband and I stayed with Ken and Michelle for 6 nights. From the convenient airport pick-up and drop-off over the lovely chats with them to Ken's yummy breakfast juices everything was perfect.
If you stay with them you can call a bedroom (bed is very comfy) and a bathroom your own. Kitchen is shared. Ken and Michelle invite you to just relax and feel at home which means exactly that. We used the pool (super cool) and enjoyed our breakfast on their balcony with super harbour views.
Exploring Melbourne was very easy as the next free inner city tram is only 5 min away (next supermarket as well, btw). I highly recommend walking into town though. The way leads you along the Yarra river with plenty of bars, restaurants, an outlet mall and magnificent views towards the city. And it only takes you 20-30 min.
We'd always stay with them again :)
