We stayed here with our 12 month old daughter and had a great time exploring Melbourne. This was our first air b'nb experience.
The apartment comes with a portacot (Child Care brand) and ikea high chair. So this was super convenient for us. The portacot was a little difficult to set up but they always are!!
The location is great. Right outside a tram stop on the 11/48 route. If you stay inside the CBD riding the tram is free.
There are plenty of places to walk to. It is about 15 mins to South Wharf DFO, restaurants on the water and the Melbourne Exhibition Centre. Another few minutes and you are at the Crown Casino.
To chill out with a little one we found a great park, Italian coffee shop and library just to the left and across the road of the apartment complex.
All in all a good trip.
