Please bear in mind that I am far from an expert on Santluz and just presenting my impressions of it as an outsider. Please do your own due diligence.

My impression of Santaluz is that its a place for people who like a perfect, pristine existence sheltered away from any diversity. It is beautiful and family friendly but to me it looks more like Phoenix than San Diego. I am a big fan of the beach areas which have a greater sense of place and of history. For me it doesnt make sense to live in san Diego and not be near the beach. I like to go to the beach sometimes just to watch the sunset into the ocean. That is why I am here. I like the diversity and funkiness of the beach areas. I prefer to live among smart, friendly folks who value those things and like to live below their means rather than wearing their means as a badge of honor.

I could be dead wrong on Santaluz but to me it is too sterile of an environment.
