Great location for exploring Melbourne and really close to Central Station. There are lots of good food options around. Bunny was very responsive to messages and was helpful.
There are a few somewhat minor things that could have provided a more comfortable and enjoyable stay:
The check in process depends entirely on strangers exiting and entering the building - so you could risk being stuck outside the building for a long time, waiting for someone to enter/exit (thankfully it seems like a somewhat busy building).
Some of the amenities weren't of good quality - the towels smelled of cigarettes, the bed was rather uncomfortable and didn't provide a good night's sleep, the tap fixtures are incorrectly labeled (the hot water was labelled as cold and vice versa), the kitchen tap is broken, the light switch in the bathroom is broken and there were bags of garbage in the buildings lobby, right next to the elevator.
