Not trying to hijack your thread, but I thought I’d chime in.
Safe? I would say its all relative to what you are used to. I used to live in LB (Channel Point Apartments right across from the campus) with a GF at the time that knew nothing, but the Orange County bubble (Huntington Beach , Newport Beach , Laguna Beach, Costa Mesa ); at first she was uncomfortable with the area but slowly warmed up to it. Are you coming from a small town or bustling city? What sort of community are you used to?
LB is extremely diverse community with many ethnic minorities commingling, does it have its seedy areas?Yes as with most cities, but what I consider safe will be different from others given my experience(I’ll let others chime in on this area of “safe”).
From Broadway to 4th street and on to 7th street you’ll find LB Arts district with many coffee shops, dive bars, and small shops; I hate putting labels on things but most people consider the crowd there as hipsters, but w/e.
2nd Street/Belmont Shores (like its counterpart in SF, this is the largest concentration of LGBT in S. CA) has restaurants,shops, bars etc… Its pretty much a main street that many locals and tourist gravitate to more so on the weekends.
CSULB being located not too far from the coast will give you access to numerous beach cities; heading south you’ll find Seal Beach AKA Mayberry by the sea / Surfside then Huntington Beach. Im comfortable in saying that the further south you head the less diverse it seems to become, but make the most of it. FWIW everyone I surf with that live in HB, prefer the diversity and access to arts/culture that Long Beach has to offer; however, on that same token they are globally conscious, culturally sensitive, and socially aware individuals.
I could keep going on, but as you can see Long Beach is pretty diverse. Like I said, more info on yourself and the type of social environment/community your are comfortable will help establish/narrow down what you may be suggested.
