Axiom Hotel
Tech-forward boutique with historic bones. Digital-age aesthetic layered over Edwardian architecture. Suited to remote workers, conference-goers, and anyone who wants Union Square access without a generic chain experience.

Why It Matters
LEED Silver certified. One of the few downtown SF hotels to deploy actual robot room service (via a bot named Astro). The building's 1906 post-earthquake architecture contrasts sharply with the deliberately tech-centric interior design. Formerly the Powell Hotel.
Axiom is a 152-room boutique hotel in a century-old building right across from the Powell Street cable car turnaround in Union Square. Previously known as the Powell Hotel, the 1906-era structure still has high ceilings, wrought-iron railings, white marble, and moulded walls — but the interior is all wired-up minimalist-chic: fiber optic WiFi, robot room service, and rooms named after units of digital data. It's one of San Francisco's more genuinely tech-forward hotels, not just in branding but in actual execution.
Where You'll Stay
6 room types available
Executive King (E King)
The top of the range at 322 sq ft. One TripAdvisor reviewer noted theirs included a sofa that folds down into a double bed — useful for a family. Two TVs, fridge, safe, and coffee machine. No dramatic views from all units, but the most spacious and well-equipped option in the building.
King
Meta Queen
Two plush queen beds — the family or group-travel pick. Ranges up to 357 sq ft. Same smart room package as the Mono with added space: 48-inch Samsung LED Smart TV, fiber optic WiFi, Illy espresso machine, mini fridge, walk-in tiled shower, fully mobile task desk, and wireless streaming for Apple and Android. Kids 17 and under stay free here.
Two Queens
Mono King
The king-bed option for solo travelers or couples who want the full horizontal spread. Ranges from 207 to 342 sq ft depending on the specific unit. Same core tech amenities — smart TV, fiber optic WiFi, Illy espresso, in-room safe. Comfortable and well-appointed.
KingMono Queen
A step up from the Nano — same tech-forward spec with a bit more breathing room. Queen bed, full smart TV setup, Illy espresso machine, walk-in shower, mini refrigerator, and USB outlets throughout. Good for a solo traveler or couple who wants space without the double-queen footprint.
QueenNano Queen
The most compact room in the house — honestly small, but smart about it. A plush queen bed, 48-inch Samsung LED Smart TV with wireless streaming, Illy espresso machine, walk-in shower, Bluetooth clock with wireless charging, and a task desk. Everything you need, nothing you don't.
QueenWellness Room
A distinct room category designed around wellbeing. Features a Dyson air filtration system for cleaner air, sound machine, aromatherapy machine, and the standard tech amenities. Meant to serve as a recovery-focused sanctuary on top of the usual connected-stay setup.

How you'll actually spend your days.
The Powell & Market cable car turnaround is literally steps from the front door. The Ride & Explore package pairs two 1-day Muni/cable car passes with a $20 gift card to The Buena Vista (famous for the original Irish Coffee at the cable car's final stop) and a Cable Car Museum souvenir patch.
The mezzanine-level Cloud Lounge has vintage arcade games and foosball. Open to hotel guests and the public. You can order food and drinks from Turn Café directly to your seat. The space holds up to 60 people for events. Record players are also available for checkout.
A small curated library in the hotel — the Hallidie Library — named after Andrew Hallidie, inventor of the cable car. Good for a quiet read or a moment away from screens.
The hotel has roughly 1,600 sq ft of event space across flexible rooms with high-speed fiber optic WiFi, integrated AV systems, and capacity for small conferences or gatherings. The Hub Rooms (1 and 2) and Cloud Lounge (up to 60 guests) are the primary event spaces.
Astro is the hotel's autonomous delivery robot. Order food and drinks from Turn Café and Astro brings them to your door — no human contact required. A genuine novelty that guests consistently call out as a highlight.
