All of those are safe and have things to do, affordability is relative and WSW QV and fairmount are pricier.

Passyunk is definitely more neighborhoody than somewhere like WSW. I constantly see people I know. You can hit passyunk, QV, and wsw in basically one long walk. Philly isn't all that massive, you can uber up to fairmount and then down to UC (or walk down the schuylkill river trail).
