I stayed at the Grand Hyatt Melbourne for 3 nights in April.... and was lucky enough to get a room with a great view. The service was good and the front desk staff was super friendly.
The Grand Club was also superb. Staff goes around and asked if guests need any hot food to accompany the drinks and snacks.
One small complaint is that there's no desk in my room. Not sure if it was just the room I had or every room's like that. It wasn't too comfortable working and I had to stretch my laptop's power cord in order to plug it on a wall socket.More
