This story is part of a CNET special report that examines the controversy gripping San Francisco as a massive influx of techies feeds an unprecedented economic boom -- and backlash.
SAN FRANCISCO -- When Brad Worrell visited San Francisco on business last summer, he stayed in an Airbnb rental for the first time in the city's Castro district. He wasn't sure what to expect. He typically stays in hotels, but his company booked him a "Castro Gem" just a short walk to the studio where he'd be working for a few weeks.
He loved it. "I thought it was a really cute neighborhood. I was psyched when I got there," Worrell says. "It was one of those classic San Francisco apartments with high ceilings."
