I stayed at Best Western Plus Sunset Plaza on my first trip and loved it. It's in a good location, has parking and is close to everything.

I personally don't love Airbnb.....maybe for New York or somewhere it's extremely expenive to stay anywhere. But there's plenty of hotels in LA that won't cost a lot of money. about 5 years ago
