The area between Union Station and Chinatown is perfectly safe. It gets a little dicey north of there, but even that I would not say is unsafe for a pair of adults. Frankly, you have little to worry about from a safety standpoint.omorrow night I'm catching a bus on 7th and H St that leaves at 3:30am. The only overnight parking on weekdays I can find for that time would be at Union Station (if anyone knows somewhere closer that would be even better). Google maps says its about a 20 minute walk, which is fine, but how safe of an area is...
