First things first, unless you have a tendency to take 1h long hot showers, there is NO PROBLEM with the hot water supply whatsoever as suggested in another review!
The flat is exactly as described, spacious, very stylish and I had everything I needed for a comfortable stay, including free apples and a cup of tea :-)
The location of the flat is behind a nice park in South Yarra and from Flinders Station it will take you about 30 minutes to get to the flat by public transport, via Uber it will obviously be much faster.
Uber from the airport will cost you about $50 AUD.
Isadora is also very responsive and helpful, Highly recommended * * * * *
