Since you mentioned Coronado(v.nice & v.expen$ive) and ~15 mile radius, a nice area with many condos/houses puts you in the La Jolla Village/University City area where I-5/405/52 intersect. Local calls it the Golden Triangle for good reasons and its about 20min. from Coronado in minor traffic. Its safe w/ chic shopping malls, close to the freeway and fairly quiet. UCSD is next door in La Jolla and there are many nice hou$e$ there. If you stay close to the coast towards north of Coronado, you won't be disappointed. Welcome to SD. We are very spoiled here all year around.
