When I stayed at the Little Tokyo Inn, it had a nightly rate of $40 as well as a weekly rate of $35 per night. It is an extremely basic hotel or motel (whichever you want to call it.) There is no TV, you share bathrooms as well as a shower, the rooms are very small, however it is a clean and safe place to stay. I don’t remember seeing any guests acting like they were sketchy or on drugs.
The Little Tokyo District is on the outskirts of downtown LA and its an ideal place to stay if you don’t have a car because its just a few blocks from union station.
