LA Pampering :-)
I'd go for Four Seasons at Beverly Hills.
Great suites with views, library, pool, dining areas, spa, fitness room, etc. Lovely lounge area, cool library, lots of greenery.
Wonderful panoramic views of the Hollywood Hills and downtown Los Angeles from the east-facing suites.
West-facing balconies offer views of Beverly Hills and the Bel Air hills.
Very high standard of interiors, luxurious bathrooms
