With a spa, a cozy atmosphere, and a convenient location for London's most exclusive shopping, the Milestone is a great boutique pick.
The Lanesborough Rating: 5.0 Pearls
The Lanesborough, a St. Regis Hotel, is a luxurious property overlooking Hyde Park in Knightsbridge. The 93 rooms have palatial bathrooms, big flat-screen TVs, and free butler service. Stately decor is inspired by the early 19th century, and free Wi-Fi and laptops are available in every room. Some rooms have great views of Hyde Park.

Baglioni Hotel London Rating: 5.0 Pearls
This boutique hotel offers an excellent location on the southwest tip of Hyde Park overlooking Kensington Gardens. The individually decorated, luxe 67 rooms all showcase classic Italian touches as well as dramatic contemporary design. Perks include free Wi-Fi and Illy espresso machines, as well as features like the spa and the Mediterranean-inspired restaurant, Brunello, which is a destination in itself. For an extra touch of exclusivity, this hotel also offers free chauffeur service in a Jaguar within a 1.5-mile radius.
The Halkin by COMO Rating: 5.0 Pearls
A 41-room boutique hotel with generous amounts of space, the Halkin exudes luxury -- from its distinctive Italian-cum-Asian interior design to its marble bathrooms with deep soaking tubs. Sumptuous and spacious guest rooms literally offer convenience at the touch of a button, as all have wall consoles for calling the butler and other services. Even the location is upscale, as the property stands in the tony Belgravia district and is just a two-minute walk from Buckingham Palace. Guests also have access to the spa at famed sister hotel The Metropolitan, since the Halkin does lack amenities such as a spa and pool.
Egerton House Hotel Rating: 5.0 Pearls
This exquisite luxury boutique hotel with just 28 rooms offers the elegance of a different time in England's history. Located in the upscale Knightsbridge neighborhood, Egerton House Hotel is a short walk from the famous Harrods Department store and renowned London museums. Rooms in this historic townhouse are individually decorated in rich fabrics, and have opulent bathrooms, free Wi-Fi, champagne on arrival, and candles at turndown. The common spaces are just as special, with a notable art collection -- including works by Picasso and Matisse -- and a gorgeous drawing room for afternoon tea.
Dukes Hotel Rating: 5.0 Pearls
Dukes Hotel is a prestigious 90-room boutique delivering an updated take on classic English luxury. It's quietly opulent and features plenty of romantic amenities, such as a cognac and cigar garden, and a Drawing Room where traditional afternoon tea is served. The most notable feature, however, is Dukes Bar, frequented by James Bond creator Ian Fleming, and the birthplace of the famous "Shaken, not stirred" line. (The bar is, naturally, famous for its martinis -- but note that there's a strict dress code.) Rooms have upscale decor that varies between room types; lower level rooms have fresh ivory and white decor, while suites blend classic and contemporary styles. All are sophisticated.
St. James's Hotel and Club Rating: 5.0 Pearls
Before St. James's was a luxurious boutique hotel, it had a distinguished past as an exclusive Gentlemen's Club. Previously owned by Sirs Michael Caine and Sean Connery -- and frequented by Winston Churchill and Gregory Peck -- this striking building on a quiet cul-de-sac in prestigious Mayfair now houses romantic, lavish accommodations. A recent multi-million renovation brought in bespoke furnishings, and rooms offer high-tech perks such as free Wi-Fi and iPod docks. An outstanding feature here is the Michelin-star restaurant directed by executive chef William Drabble. The hotel is also filled with notable Cubist paintings and offers close proximity to shopping and galleries. Though it lacks a spa, the St. James's does offer spa packages at the nearby Elemis day spa.
Draycott Hotel Rating: 5.0 Pearls
This 35-room combo of Edwardian townhouses is warm and intimate with a country home feel, and in a great location for exclusive West End shopping. With wonderful boutique perks such as the free English afternoon tea (guests at other hotels will have to pay at least a £15 premium to enjoy such a tradition), free pre-dinner champagne, and free hot chocolate before bed, it's hard to find much at the Draycott to complain about. Unless, of course, your priorities are a pool and fitness center, both of which the hotel lacks. However, rooms are top-notch: Comfortable and spacious, each one is themed and styled after a prominent figure in English theater. Biographies, portraits, and even a small dossier are provided to help familiarize you with your highlighted actor or actress -- a brief but delightful introduction to the world of English drama.
Cadogan Hotel Rating: 4.5 Pearls
The Cadogan is an unpretentious boutique hotel with a prestigious Knightsbridge address. This 64-room hotel occupies a historic Edwardian townhouse on Sloane Street, in close proximity to local shopping. The property has a rich history, including the room where Oscar Wilde awaited his arrest in 1895 and another where King Edward VII met with his mistress, the British actress Lillie Langtry. The Cadogan creates guest profiles to take note of personal preferences, and classy rooms are full of character with antiques, dramatic curtains, and luxe bathrooms. Guests craving modernity will be happy to see big flat-screen TVs and iPod docks. The hotel also offers an excellent restaurant, Langtry's, named after the actress. With a small fitness center and personal service the Cadogan is an appealing pick, although some guests consider rooms to be a tad small and complain of street noise.
