Central London escorts across W1, WC2 and SW1, all night long

W1 is the West End proper: the hotel squares of Mayfair, the narrow streets of Soho, the village high street of Marylebone and the shopping mile of Oxford Street stitched between them. WC2 takes over east of Charing Cross Road, with the market halls of Covent Garden, the opera house and the Strand running down towards the river. SW1 is the stately half, government on Whitehall, palaces and parks, then the cream stucco of Belgravia and the department store lights of Knightsbridge. Beyond these, our map keeps going west along the park, to Paddington in W2, Kensington in W8, South Kensington in SW7 and Chelsea in SW3.

None of it is far. On a clear night a taxi from Marylebone to Chelsea takes about twenty minutes, and a companion who lives in one district can be in another before your first drink is poured. That closeness is why we keep the route this tight: every address on it sits inside Zones 1 and 2, so her journey is always part of the fare.

Around the West End there is Mayfair for grand hotels and quiet mews, Soho for late tables and live music, Covent Garden for curtain up and the Savoy, Marylebone for unhurried dinners, and the West End itself for the lights of Piccadilly Circus and Leicester Square.

Down through SW1 come Westminster for river views and conference weeks, Victoria for late trains and the Gatwick Express, Belgravia for embassies and hushed squares, and Knightsbridge for suites above Hyde Park.

Out to the west you will find Paddington, where the Heathrow Express pulls in, South Kensington among the museums, Kensington along the High Street and the palace gardens, and Chelsea on the King's Road.

Our companions walk into the grandest lobbies in the city and the smallest boutique townhouses, always as your guest and never through any arrangement with the hotel. In Mayfair that means Claridge's, The Connaught and The Dorchester. On the Strand it means The Savoy and One Aldwych. Marylebone has The Langham on Portland Place, Belgravia has The Goring and The Berkeley, Knightsbridge has The Bulgari Hotel and Mandarin Oriental Hyde Park, and out west there is Royal Lancaster London above the park and The Milestone on Kensington Court.

Serviced apartments and private homes are visited on exactly the same footing. Tell the desk about the building, whether there is a porter, a concierge or a key code, and she arrives prepared for it.

Once your booking is confirmed in writing, a companion is usually with you within the hour anywhere on this map. The inner stops are quickest: Mayfair and Soho typically take around 35 minutes, and Covent Garden, Marylebone, Belgravia and Knightsbridge around 40. Westminster, Victoria and South Kensington run nearer 45 minutes, while Kensington, Chelsea and Paddington take about 50, a little longer on a busy Friday or Saturday.

Those are honest, typical figures rather than a stopwatch guarantee. The desk gives you the real estimate when it confirms, and messages again the moment she leaves.

Write on WhatsApp or Telegram with four details: who you would like to meet, where you are staying, the time and the length of the evening. Your full name, hotel and room are verified once, over WhatsApp, and never asked for again. A quarter of the fare, 25 percent sent by bank transfer, then secures a standard hotel or residence visit, which is simply how a serious agency makes an evening certain for both sides. Overnights, events and trips away are held with half, and the slice of that half covering travel is non-refundable.

One hour starts at £400, two hours are £750, the four hour dinner date is £1,300 and a ten hour overnight is £2,400. Whatever remains is paid on the night, cash in hand or by transfer, as you like. Plans change, and with at least three hours' warning a standard booking is released at no charge; cancel inside two hours and half the fee applies, while not turning up at all means paying the whole of it. The complete booking steps have a page of their own.

Visitors spending a few days of meetings in the city who would rather not eat alone. Residents of a quiet flat off Marylebone High Street or a mews house in Belgravia who want an evening that never leaves home. Travellers stepping off the Heathrow Express at Paddington or the Gatwick Express at Victoria at an hour when the city has gone quiet. Theatre lovers who want someone beside them for the second act and the supper afterwards. What they share is a liking for plain arrangements, a known fare and a companion who looks exactly like her photographs, which is why every portrait on the site is checked against the woman herself.

Our companions are spread along the route, so there is nearly always someone close. Mayfair is home to Angelika, Luna and Samanta. Soho has Jasmin, Molly and Tiffany. Covent Garden has Karolina, Nancy and Tina, and Marylebone has Liana and Rosa.

Along SW1, Lea, Patricia and Violetta live in Belgravia, Bianka, Margo and Sonya in Knightsbridge, and Lucy and Roxi in Pimlico, a short walk below Victoria. Out west, Laura, Nora and Vanessa are Paddington locals, Danielle, Milena and Thea live in South Kensington, and Cindy, Michelle and Stacy call Chelsea home.

Half past seven, a glass of wine in the bar of your hotel on Portland Place while Broadcasting House glows across the road. Half past eight, dinner on Marylebone High Street. Eleven, a black cab down through Mayfair, past the lit windows of Bond Street, to hear the final set in the low red light of Ronnie Scott's. After midnight, the long quiet ride back with the night buses sliding by, and a nightcap in the room. Taken as the dinner date booking, that whole loop is £1,300; stretched into an overnight, it runs on to breakfast.
