Los Angeles, which is most ideal for me?

I’ll be starting a new remote job this summer in California so I’m looking for possible areas to live in?

Im live in NJ and currently work in NYC, so Im looking for something urban rather than the suburbs. Walkability is a huge plus for me. I’m 24 and single so I also want to be in a similar demographic neighborhood. My budget is $1.5k - $1.8 with roommates
