Just returned from a 1 night stay at the PH. As far as PH goes, this one is up to par, but nothing special.. They renovated the rooms and work out room - great job. Service throughout the hotel is also great. Compared to a stay 2 years ago, it is a different hotel.
Also spent one night at the Beverly Hilton which is the sleeper. If you can get one of thier Penthouse suites, go for it. Lots of great nice touches like valet putting bottled H20 in your car, Evian in the workout room, etc.
Agree with above posters that Peninsula is a notch above.
