I stayed here with my family recently and had an excellent experience!
Will provided clear and thorough instructions prior to my arrival, and also checked with me beforehand about a potential change to the configuration of a room (install a bunk bed) from what was listed at the time that I booked. He was very responsive in the lead up to our trip and also met us at the apartment to hand over the keys and guide us through check-in.
The apartment was modern and comfortable, with everything that we needed for our stay. This included things like towels, coffee machine + pods, an iron and a hair dryer.
It's very close to the Elsternwick station and very straightforward to catch a train in to Flinders Street Station in the city. One thing to be aware of is that the apartment overlooks the Sandringham train line, so there is a bit of train noise overnight.
