Langham Hotel London Rating: 5.0 Pearls
Luxurious, stately, and composed, this 380-room hotel projects an air of exclusivity. The hotel blends a certain quintessentially English air of prestige without the usual pretention, and has all of the luxury amenities one could hope for. With gorgeous, classically decorated rooms, an in-house book butler, a spacious fitness center, and a premier location for West End shopping, this is a good place to be. The beautiful Chuan Spa, 16-meter pool, and salt sauna just adds to it's romantic vibe.
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. Romantic hotel highlights include fine dining at the Michelin-rated restaurant Apsleys, a small spa studio, a ground floor piano bar, and traditional afternoon tea.
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 extra romantic hotel 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 Milestone Hotel Rating: 5.0 Pearls
The Milestone is perhaps the most famous boutique hotel in London, and certainly lives up to its expectations, with exquisitely designed rooms and exceptional service. The service is where the hotel really shines, as each member of staff is superbly trained, which helps ensure guests get the first-rate luxury experience for which The Milestone is known. With a spa, a cozy atmosphere, and a convenient location for London's most exclusive shopping, the Milestone is a romantic boutique pick.
Sanderson Rating: 5.0 Pearls
The Sanderson is an edgy hotel with original and extravagant design by Philippe Starck. Innovative rooms feature a mostly all-white color palette designed without interior walls. There is an emphasis here on texture, seen in the layers of sheer curtains that divide different areas of the room. Design touches include carpets with Voltaire's handwriting and some of the sexiest bathrooms we've seen, some with separate walk-in showers and freestanding soaking tubs. There are many hotel highlights beyond the rooms, including an all-white tranquil spa with 14 treatment rooms and meditation beds. The restaurant, Suka, serves Malaysian food, and a Mad Hatter's themed afternoon tea is served in the striking courtyard.
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 (which our top five romantic hotels do have), the St. James's does offer spa packages at the nearby Elemis day spa.
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 and romantic.
