Underwhelming
I stayed here for two nights assuming with my Hyatt status I'd get a better experience than a non-status guest at the Pan Pacific where the rest of my party was staying.
The Hyatt Olive8 had very unprepared employees and they had to ask multiple supervisors and managers for even the most basic things, such as to make a key to replace a lost one. In addition the room I was in had a slanted desk and the floor was not flat (I thought it was an optical illusion but I used a level). They put me in to a suite but the suite was underwhelming and the view was of a movie theater with huge bright lights.
The only real redeeming quality of this place was a nice concierge and great free breakfast when you qualify for that benefit. 
This hotel is extremely overpriced and is the worst Hyatt I have ever been to without a doubt. I will not be returning.
