The 148-room Mandarin Oriental in Back Bay offers some of Boston's most luxurious standard rooms, plus a 16,000-square-foot spa and extraordinary service. It has no pool; and the views aren't as grand as those at the high-end properties on Copley Square. But it's as special as any hotel in Boston -- and a clear winner if you prefer contemporary to traditional decor and ambience.

One of the city's top hotels with amazing service, a parkfront location, a great health club with a beautiful pool, and an iconic restaurant, the 273-room Four Seasons offers luxurious and spacious rooms with stunning granite bathrooms. But there's no full spa on-site.

With impeccable service, some of the biggest guest rooms in Boston, and a phenomenal gym, spa, and lap pool, the 230-room Boston Harbor Hotel is among the city's most luxurious hotels. The restaurant is celebrated for its extensive wine collection, and the harborside location means gorgeous water views from many of the rooms.

The Boston Ritz-Carlton is refreshingly intimate with spacious, luxurious standard rooms and access, for a fee, to one of the city's best gyms, with its own spa, salon, and pool. But it doesn't thrill stylewise, service is uneven, and the restaurant is unremarkable.

A 63-room hotel with exquisite service, a genteel but easy-going vibe, and a beautiful location in residential Beacon Hill, Fifteen Beacon (or XV Beacon) blends historic New England elegance with modern, minimalist design and hi-tech amenities. A great fit for discerning business and leisure travelers.

With large, playfully furnished rooms, the 236-room Hotel Marlowe is one of Cambridge's most family-friendly hotels. Its neighbor, the Royal Sonesta Hotel, is cheaper and has a pool, but the Marlowe offers a boutique-like feel at a reasonable price, with personality to spare.

This cozy, 225-room hotel in a beautiful old building -- the former police headquarters -- is full of nice touches, from hot towels at check-in to free Wi-Fi in rooms. Sure, rooms aren't huge and the tiny fitness center disappoints, but beds are luxurious, the bar is lively, and service is lovely. Quite nice for the price.

Boasting the city's only rooftop pool, this 285-room Back Bay hotel offers spacious standard rooms with floor-to-ceiling windows, a fitness center with South End views, and an affordable French brasserie. Score a cheap rate, and it's worth it -- despite the lack of 24-hour room service and the daily Wi-Fi charge.

A former Federal Reserve bank turned luxury hotel in the grey, sterile Financial District, the Langham boasts immaculate, distinctively Bostonian rooms (with flat-screen TVs and Wi-Fi), spot-on service, and a stellar spa, but significant street noise keeps it from attaining perfection.

Bought from the Ritz-Carlton in 2007, the Taj Boston holds on to the Ritz' elegant look, but also offers some superb perks, like chenille bathrobes and free rides in the house Jaguar. Given its free business center, well-equipped gym, and ideal location bordering the Public Garden and the swank boutiques along Newbury Street, it's an excellent luxury pick.
