A surprising gem
I really enjoyed this city. The city centre itself looked a bit run down and scary, as most US cities do. However, the scenery was absolutely stunning. You should rent a car and get out into the hills...and keep on driving til you get to the desert. Not often you find somewhere where you can experience lush hills and trees, beach, and desert! Hollywood is not as great as it sounds, and relies too much on its past. "This is where such and such used to drink" is a usual phrase.
Insider Tip:Just avoid the city centre and head to the beach and mountains. Public transport is awful so rent a car - they're cheap.
