Haniff is really the best host, his username isn't a lie.
I found the greatest value with the turn around on communication time, I didn't have many issues at all during my stay but I know if I did, Haniff would get back to me within 5 minutes of me messaging him.
He also got me donuts for breakfast one day, super randomly. It was a very sweet gesture.
The place itself was very clean and smelled nice 24/7. The bedroom was nice and cozy, the bathroom was large and spacious. It was a shared bath but I never had issues with having to wait for other people. There's also a seperate toilet just in case.
Location was amazing - but there is a tradeoff for being right in the middle of the city. If you're a light sleeper you might want to bring ear plugs as there will be noises from the city around the clock. It's a pretty small price to pay for such a good location (10 minutes walk from all the good stuff in Melbourne city).
