Flat: This was my first try with AirBNB and Richards place was exactly as described - not big, but very cozy. There is plenty of storage space and actually all what you need in everyday life. The Big plus was shortage of any kind of TV - if You have SUCH panoramic view from Level 59, TV is crime against sense.
Location: It just can't be more center located. This IS the best location for any traveler in Melbourne. You can see from above (no need even to leave bed) where SkyBus is coming to the SouthernCrossStation. And entire Southern Cross, Yarra River and Etihad stadium is below you. If You need location, location, location - this is it.
Host (Richard): It's worth to mention that my plane was delayed for 4 hours and I was coming at midnight - Richard was awaiting on SkyBus stop just to show how to find flat for first time. He is so easygoing that You will be feeling him ore like old time friend than host. Richard is a very good man!!!
P.S> I enjoyed every single moment at Richard's place.
