My son lives in the South Bay area of LA so I have been out there a lot. I don’t have any input on which hotels would be convenient – I particularly like the Manhattan Beach Marriott and the Beverly Hills Marriott. HOWEVER my impression is that hotels are incredibly expensive in southern California. When I have stayed in a less expensive one (read: <$250/night) I have hated it. And I am not that picky – I just want clean and comfortable!
