This building is in a great location, close to everything. The rooms have awesome views (we were on level 43). It's extremely quiet and the beds are comfy. Small, but great value if you don't need somewhere big. I would definitely recommend staying here when visiting Melbourne.
There were a few negatives, they didn't seem to clean our room very well before we arrived - there was pubic hair and bits of rubbish on the bathroom floor, and beside the bed was dirty. The bathroom set up is pretty annoying because there's no shower screen and the entire bathroom gets very wet, so I'd advise putting the bathmat outside the bathroom door. Also, we didn't use the TV because it can only be used for netflix and you have to buy your own subscription. However, I would say that these negatives were relatively minor issues, and were definitely outweighed by the positive aspects of the room.
