San Francisco’s classic Union Square collides with modern tech culture at this restored turn-of-the-century hotel. The 152 guest rooms with urban sentiments, like ceilings with exposed pipes and lighting fixed on cables, bring the former Powell Hotel into the modern era. Plenty of tech-forward amenities attract young, wired travelers, including a mezzanine nicknamed Cloud tricked out with nostalgic arcade games and meeting spaces that can easily be divided into two areas called Hub 1 and Hub 2.
