I just spend the last 3 night at this Grand Hyatt in Melbourne and that is my preferred choice in Melbourne as the location is great easy to walk around to plenty of places. The service is very good and the staff is excellent. The breakfast buffet in the gigantic opened kitchen is very nice.
The room are very well appointed and spotless. My "only" negative comment is the TV lineup needs more international selection. If you need to be there for business or pleasure great hotel.
Yes not the cheapest one in town but you pay for what you get.
