The Vibe: Laid-back, this century-old hotel combines San Francisco’s passions: tech and sustainability.

The Area: Union Square.

The DNA: The LEED-certified, hight-tech Axiom Hotel was designed for guests who desire a digital lifestyle delivered through seamless technology: iPad-assisted check-in, complimentary fiber-optic WiFi and easy access plug-ins to mobile devices. Room choices are based on size and floor plan and named after tech bytes including Nano & Mono Queen, Meta Queen, Mono King and E-King. The mezzanine level—named the Cloud, a nod to the hotel’s digital influence—features classic arcade games that further fuse vintage entertainment with present-day gadgets.

Suite-Me-Up: This being San Francisco, rooms are not large, but soft mood lighting and the homey bedding to the marble bathrooms and amenities including an Apple TV, a digital news service, a bluetooth clock radio, and Illy espresso machines should work out for you.
