The neighbor is fairly quiet (for an apartment so close to downtown LA) and I did not see much people walk by or possibly doing anything suspicious. I feel pretty secured in the morning and at night. It has all the thing you will possibly need for a short term vacation in LA. But this is a old-fashion apartment unit in LA, no laundry machine in unit or on site is anticipated, so I suggest either you pack extra clothes or you find some soap to wash your clothes before you run out if you are looking to stay for more than a week.
Closing comment:
Fantastic place for short term vacation, but long term vacation will need some plan ahead.
