The first Nine Hours opened in 2009, and while it's part of the Japanese capsule hotel phenomenon that started in the '70s, this chic, modern version helped kickstart the modern micro hotel trend. The people behind Nine Hours asked a simple question—what do you really need in an overnight stay in a busy urban center? A place to shower. One hour. Check. A place to sleep. Seven hours. Check. And somewhere to get dressed the next day. One hour. Check. Nine Hours has it all, in about as compact a space as you might imagine.
