I had a pleasant stay at Park Hyatt Melbourne. The receptionists and service staff were very friendly and polite. Also the rooms were very clean and spacious. I also liked the fact that there is a TV at the big bathtub... definitely great for relaxing!!
Only thing is that they could look into the electrical circuitry of the room. The lights flickered and turned themselves on and off. The TV turned itself on at night too. I wouldn't attribute it to anything supernatural but it might
scare other guests.
