Proper Hotel San Francisco

Don't let the name fool you - guests here are anything but prim. Dubbed "the hippest hotel in San Fran" by Condé Nast Traveler, this uber trendy spot is loved by cool kids (including the likes of LCD Soundsystem, who recently booked a stay). Situated in the SF version of the Flatiron Building, the Kelly Wearstler-designed property boasts a buzzy rooftop bar as well as high tech amenities.
