The Peninsula is where San Francisco's wealthiest families came to slow down, a century before tech ever showed up. Tree-lined streets, real downtowns, and single-family homes with actual yards define the corridor from San Bruno to San Carlos. Each city has its own personality: Burlingame's two downtowns and top-ranked schools, San Mateo's restaurant scene and value, Millbrae's transit hub, San Carlos's small-town charm. I'll help you find which one fits.
