Loews Regency San Francisco provides unbelievable views, astounding rooms, and first-rate service in the Financial District. Those incredible views take center stage, but the property does more to deserve its place as one of the city's best luxury hotels. The rooms are some of the city's most spacious and best appointed, with luxury details from featherbeds to marble bathrooms with separate showers and large tubs. High-quality services, including free welcome tea, use of the house car, free overnight shoeshines, and evening turndowns, help cement its luxury reputation. The hotel itself is unobtrusive, and could be mistaken for an office building. It's one of the top choices in the city for business travelers, but luxury leisure travelers will also find plenty to appreciate.

From the dedicated concierge available throughout the day to the extremely attentive servers at its two-Michelin-star fine-dining restaurant, Taj Campton Place provides service par excellence. Elegant rooms meet the bar set by the hotel's service; all have flat-screen HDTVs, Nespresso coffeemakers, and double-paned windows that keep the traffic noise outside. The plush, pillow-top beds feature Frette linens, feather duvets, goose-down pillows, and orange Indian silk throws, as well as retractable reading pin lights on the cushioned headboards. Turndown service and twice-daily housekeeping are provided, and 24-hour room service is available. Free morning coffee, tea, and baked goods are set in the lobby bar, and free Jaguar car service is available. The hotel's modern, open-air gym is open 24 hours, and free Wi-Fi is available throughout.

The St. Regis offers the best in luxury, with some of the best hotel service in town. A large staff prevents guest pileups at the front desk, concierge, or anywhere else, for that matter. Doormen in top hats tip off the front desk to a guest's arrival through walkie-talkie headsets. And perhaps best of all, 24/7 butler service (for suite rooms, only) is a touchscreen tap away -- a staff member will do everything from collecting shoes for a free overnight shine to delivering toiletries, newspapers, or dry cleaning to making reservations. Rooms are modern, beautiful, huge, comfortable ... need we go on? Compared to the smaller, stuffier rooms at competitors like the Ritz-Carlton and Four Seasons, these rooms are refreshingly modern and high-tech. Amenities like mini TVs in the bathroom, separate tubs and showers, and huge flat-panel TVs match or surpass what you'll find in the best rooms in the city. 

In the heart of San Francisco's Financial District, Omni San Francisco Hotel is well-positioned for both leisure and business travelers and within walking distance of everything in downtown. Even business travelers who don't need to take advantage of the Omni's central location or the ample meeting space will still appreciate the hotel for its terrific service, popular steakhouse, lobby bar, and free Wi-Fi (if you sign up for the loyalty program).

Everything you'd expect from a Ritz is on offer here -- formal and doting service, conservative decor, fine dining, a luxury spa -- all in the ritziest of San Francisco neighborhoods. Rooms are spacious by San Francisco standards (the most basic start at 400 square feet) and are well-appointed, with good-size desks and comfy armchairs. But while luxury competitors offer free Jaguar car service (Taj Campton Place), 24-hour butlers (St. Regis), or panoramic views (Loews Regency), the Ritz lacks a wow factor. 

Club Quarters Hotel in San Francisco is different from a typical hotel. It offers memberships to businesses and nonprofits that agree to pay for a certain number of nights every year. Nonmembers can also book rooms, of course, but it can be hard to find an available room on a weekday -- not ideal for most business travelers. However, due to the steady revenue stream, weekend and holiday rates can be much lower than what you'd find at other hotels in San Francisco's Financial District, especially for a studio or one-bedroom suite with an in-room kitchenette. Service is minimal -- no doorman, no concierge, and no valet parking.

With a location in the heart of the Financial District, classy meeting spaces, a solid business center, two on-site restaurants, a hopping bar scene, and free Wi-Fi in public spaces, Le Meridien stands out among business-friendly San Francisco properties. Rooms feature all the extras of a five-pearl lodging --- from bathrobes, Frette linens, and 24-hour room service to a well-stocked minibar, a large work desk, and overnight shoeshines -- plus there's an on-site fitness facility.

In the Fairmont San Francisco, business folks find all the cachet that a turn-of-the-20th-century grand dame in a ritzy Nob Hill location offers, coupled with the up-to-date amenities and services of the present. It's chock-full of conveniences like a well-equipped, 24-hour business center — staffed Monday to Friday — a concierge who's on duty throughout the day, a fitness center, thousands of square feet of meeting space, an on-site UPS store, high-end shopping, and a cable car stop right outside for whisking guests around the city. The elegant rooms have Wi-Fi (free for loyalty program members), pillow-top beds covered in Frette linens, deep tubs, plush robes, minibars, snack baskets, iPod docks, 24-hour room service, and, if you really must work, large desks.

You can't ask for a closer location to the Moscone Convention Center than this W outpost in the SoMa Art District. Aside from a quick morning commute for convention-goers, the property offers a responsive, on-site concierge and rooms with an extensive pillow menu -- body pillows, neckrolls, firm foam PrimaLofts, feather-filled -- plus bright work desks, minibars, iPod docks, 24-hour room service, and Wi-Fi (charged daily, though it's free in public spaces). Add the 24-hour fitness center, heated lap pool, 5,000-square-foot Bliss Spa, and a restaurant with an award-winning wine list, and this becomes a stellar choice for the corporate crowd.
