Definitely a 5 star property if you are on holiday or are traveling with a family (the apartment is completely childproof, and has tons of family oriented amenities. However, not a great place for a business traveller, particularly if you want to work in the apartment. None of the tables that would be good to work at have power outlets near them, and working from the couch is pretty uncomfortable (I ended up working from a cafe most days). Kitchen was a bit basic but suited my needs (no real reason to cook when in Melbourne, the food is fantastic).
Location is pretty amazing. It's about two blocks away from the river, which is a nice insulation from the tourists but still means everything is accessible via just walking. The crown casino is quite close by and has 24 hr eats (although I'd recommend going elsewhere if you are price conscious). The apartment is about a 5-10 minute walk from the free tram zone.
Check in/check out was super easy. Host provided a number of food recommendations that were spot on.
