Westside Rentals is a great source. You might also want to check the Argonaut, a local Westside paper that has rental listings.

Oh, and welcome to LA. I’ve been here for two months (job relocation) and I absolutely must say it’s the worst the city I have ever lived in. Traffic is horrible, rent is so high for so little, utilities are outrageous, and the city has no culture.

Welcome! 🙂
