Based upon the additional information the OP has shared–I would again suggest Carmel Valley and Del Mar–especially considering the price range, schools, freeway access, and the Coronado connection. JMO.
We own rentals in both CV and DM, and a couple of the families who lease from us are from the East Coast, and love both locations.
Agree that Sunset Cliffs and parts of Point Loma could be great considerations for the OP with excellent proximity to Coronado. Several family members live in both, but I think other posters have covered the pros and cons that exist there, which should also be considered. University City is also a great option, as UCGal mentioned.
Although we’re San Diego natives, we’ve lived all over the country and the world, but always come back to San Diego–so that should tell you how much we love it, and I think you will too!
