Opened in June 2013, The Nadler Soho is a 78-room, boutique hotel in the heart of London's hip and sultry Soho district. Business travelers and wealthy leisure tourists alike will appreciate the hotel's convenient location and the emphasis on style with quality products and amenities. Lower-category rooms can be a small, but upgrades buy more space, Nespresso machines, and better views.

The 17-room Best Western Maitrise Suites Apartment Hotel is an unassuming, upper-middle-range property set on the high street in the West London neighborhood of West Ealing. While its suburban location offers little in the way of tourist attractions, a nearby train station is convenient for connecting to Heathrow Airport and Paddington Station. The spacious apartments are clean, contemporary, and equipped with full kitchens, well-maintained bathrooms, and living areas with flat-screen TVs; some have washing machines. There is no restaurant on-site. For somewhere with a little more character, take a look at the nearby Drayton Court, which has a historic pub with a huge beer garden.

This Citadines Prestige is an upscale six-floor hotel with 192 apartments on an attractive, historical (but busy) road in central London. A full 2010 renovation tastefully modernized interiors whilst maintaining a homey, relaxed vibe. Apartments are sleek and clean with kitchens and modern bathrooms -- though toiletries are wall-fixed in some. Despite the hotel's name, Covent Garden is a bit of a stroll away, though local transport links are excellent. Overall rates are standard for pricey central London, though a self-catering option means you can at least save on eating out.

This upscale 44-room boutique hotel is located on a quiet residential street in posh Marylebone, a short walk away from top sights like the Sherlock Holmes Museum and upscale shopping on Marylebone High Street. Rooms have dapper decor, Sky HD TV packages with hundreds of channels, and even furnished courtyards in some. The upmarket Italian restaurant Dieci serves round-the-clock fare, while the handsome cigar bar listed among the city’s best is a destination in and of itself. Visitors looking for more family-friendly digs in the neighborhood can opt for the four pearl Thistle Marble Arch. 

This 63-room hotel has retained its original beautiful Victorian architecture and ornate period furnishings in the common areas -- but the rooms are generically furnished, worn, and have a corporate feel. Nevertheless, its unparalleled central location and exclusive status as the only mid-range (read: affordable) hotel in the vicinity mean a relatively reasonable option in the very teeth of London's tourism beast. There's no pool, though, so young travelers may be disappointed.

Harrington Court Apartments is a residential-style hotel, offering 47 apartments with fully equipped kitchens, plus conveniences like washers and dryers in most units. Its South Kensington location is excellent, within walking distance of many shops, restaurants, and attractions, and the tube station is just a minute away on foot. Apartments are modern and fresh, with attractive and simple decor, while some have balconies overlooking the street. Guests are welcomed on arrival with a basket stocked with snacks, sweets, and fruits, and the reception and concierge desk is available 24/7. Guests receive free passes to the local gym, but there's no fitness center on-site and other services are scarce. Travelers who prefer more hotel amenities should consider the Radisson Blu Edwardian Vanderbilt, which has period charm and lower rates.

The central, exclusive Metropolitan by COMO is located at the nexus of Hyde Park, Knightsbridge, and Mayfair. Known for the excellent Michelin-rated restaurant Nobu and nightlife hot spot Met Bar, this hotel is a chic, upscale option. Rooms are sunny and spacious with flat-screen TVs and coffeemakers, and the contemporary lobby is home to a knowledgeable concierge service. The small, but well-equipped spa and fitness center along with free Wi-Fi are perks here, but rates are pricey.

Featuring only 29 rooms, this quaint-and-cozy boutique hotel offers an inviting, intimate experience in the middle of the posh residential neighborhood of Knightsbridge. As to be expected with a tiny boutique hotel, rooms lack extra space, but the decor is fresh and modern with neutral colors and the occasional designer-like touch (like stacked glass-ball lamps and pretty patterned wallpaper) -- though the random uninspired watercolor paintings feel a bit misplaced. Perhaps because of the surrounding area, rooms rates are here are above average despite the fact that rooms are missing some basic amenities (like a mini bar). But the free daily traditional English cream tea with homemade scones and the open bar in the evenings are definite perks.

Brown's Hotel, located in prestigious Mayfair, is part of the luxurious Rocco Forte Collection. The hotel is made up of 11 historic Georgian townhouses and no two of the 117 rooms are the same. Spacious, elegant rooms have a soft, soothing color scheme along with stocked minibars, big flat-screen TVs, and upscale bathrooms (some have a separate soaking tub and walk-in glass shower). Hotel highlights include quality dining and drinking venues such as HIX at the Albemarle, the English Tea Room, and the Donovan Bar. With a spa and fitness center, Brown's has all the features guests would expect at this price point.

The Parkcity hotel is a small corporation-run hotel with a sleek, contemporary lobby, restaurant, and mocktail bar/lounge. It’s relatively affordable, well located for direct trips from the airport, and a short walk to the nearest tube station (for access to area attractions). But minimal room amenities and basic facilities may leave some guests wanting more.
