If you need a good place to rest,a friendly and very helpful host - stay here!
It's a bit outside of L.A.,but the bus is just across the street and within 25-30Min. you are at Union Station and can go anywhere you want to go.
The area is very quiet,there are only a few shops,but if you have or rent a car,it's easy to travel.
Writing (and later speaking) with the host was awesome,you can ask her for anything and she'll try to help.
Would recommend this esp. to students,backpakers and just people that like to go sightseeing alot,but want a comfortable bed,kitchen to cook and place to shower. :-)
