The Mission Hills and surrounding area (inc. parts of Bankers Hill, Morley Field, parts of Hillcrest, western part of University Heights around Park) I think is the best place to live in San Diego. It is one of the few areas in San Diego County that has at least a little bit of character, historical charm, pedestrian oriented neighborhoods, mom & pop stores. And so centrally located.
As compared to say North County inland east of 5 (where I live now…can’t wait to move back towards Balboa Park!), that is the exact opposite…cookie cutter homes, strip centers with mostly national chains, 100% car oriented, hardly anyone walking the sidewalks. Completely lacking in any character, charm or soul. “Phoenix By the Sea”. Man they used to build much cooler neighborhoods in 1890!
