I agree with DrScopio. That place is not located in a good area of town. Try to get one that's within the part of the recommended convention hotels. It'll be much safer, and you'll get access to a con shuttle. Remember, just because it's cheap, it doesn't mean it's safe. (This is downtown LA after all, and gangbangers do hang out in certain areas that's close to the convention center. There is reason why some security officers in those areas are armed with guns.)
However, avoid booking the Figueoroa hotel at all costs-Unless you like bed bugs & cockroaches crawling all over you & sharing the bed with you at night.
