Stayed at Judy & Vince's place for a few nights and found it to be a great place to base yourself while exploring Melbourne.
The location was fantastic; not too far from where the action is in Nth Melbourne, but also easy to get out of the city if you have a car; there are a few ways to avoid the CBD if you need to get out and the location is close to all of them. If you like swimming, the apartment is 5 mins walk from North Melbourne swimming pool.
The apartment itself was larger than expected, with a large kitchen we used to cook meals when we didn't want to go out for dinner. Lots of space in the lounge to hang out or down the hall (on the same floor) to get to the lovely patio shown in the photos. The underground garage was good to have too, and while it wasn't "spacious" it was much easier to get the car in/out than other apartment garages we've stayed in in Melbourne.
We'd definitely consider staying next time we're in Melbourne.
