Hacker hostels in Silicon Valley offer short- and long-term stays for future startup stars

From the outside it's just a beige three-story building in a quiet residential neighborhood. But inside, in a third-floor apartment, there are enough Ikea bunk beds to sleep 10 people, crammed into two bedrooms.

The living room is bare except for a futon, a tiny desk and laptop power cables strewn across the hardwood floor like a nest of snakes.

The tenants, mostly men in their 20s, sleep next to heaps of dirty laundry. There is no television set; the men watch online video, on laptops with headphones.
