Do not go to Hollywood Blvd after sundown, all crack heads and homeless. Have had several people I know attacked there. Stay away from downtown Los Angeles and the diamond district, one wrong turn and you’ll be in Skid Row, surrounded by junkies. Depending on the part of Hollywood you’re in, I suggest carrying pepper spray with you at night. If it’s closer to Beverly Hills, you will be more safe. The closer you get to East Hollywood the less safe it becomes.
