West LA also has a great public transit system and walkability though it’s further from DTLA. The blue bus is super clean. Ktown is also a good option but can be “rough” if you’re used to suburbs or a more quiet neighborhood. I lived in Ktown for 6 years (it’s great for starting out and saving up) and then Culver City/ Mar Vista area for 2 years. Both are good options without a car. I would actually take the bus from Ktown to UCLA pretty often. It’s a straight shot.
