Home to elegant loft apartments and some of the world’s biggest tech start-ups, SoMa is emblematic of the new wealth that has made the city such a desirable place to live. Techies and entrepreneurs run rampant here; Twitter, Uber, and AirBnb all have their headquarters in the neighborhood. Meanwhile, artsy types can hang out in one of several stellar museums or in former warehouses that have been repurposed as hip boutiques, galleries, and cafes.
