What about La Jolla?
If you rethink your requirements – just 4 bedrooms but spacious ones – La Jolla IS the most convenient in terms of commute (or as good as Torrey Hills). Schools are excellent. If money is no object, there are some nice houses around La Jolla SCENIC Drive – that where my UCSD ex-boss (faculty) lived – and the commute is really sweet. Torrey Pines elementary had the highest API in 2010 in SDUSD. Even more towards Mt. Soledad and downtown La Jolla are not that far from UCSD and you commute on city streets.
