Escorts in Central London: ring the bell by Piccadilly Circus, W1, WC2 and SW1

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 the map, although the traffic keeps its own clock, which is why the desk allows roughly an hour for her ride once it has confirmed. Our companions know those streets the way a regular knows the stops on the night bus home. 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 Strand hotels, 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 W1K 4HR, W1K 2AL and W1K 1QA. On the Strand it means WC2R 0EZ and WC2B 4BZ. Marylebone has W1B 1JA on Portland Place, Belgravia has SW1W 0JW and SW1X 7RL, Knightsbridge has SW7 1DW and SW1X 7LA, and out west there is W2 2TY above the park and W8 5DL on Kensington Court. The address stands in for the name throughout.

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, plan on about an hour before she reaches you, wherever you are on this map. Mayfair, Soho, Covent Garden and Marylebone keep to that hour on an ordinary night; Westminster, Victoria and the Kensington side of the route often run past it, and so does every stop when the rush is on or the West End is packed on a Friday or Saturday. Beyond Zone 2 the ride is longer again, and a Heathrow hotel is an hour and a half or more away.

That hour is an honest planning figure rather than a stopwatch guarantee. The desk gives you a real estimate when it confirms, then drops her time into your WhatsApp or Telegram conversation as soon as she is aboard.

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. The desk then writes the companion, the start time, the length and the fare into one message, which is simply how a serious agency makes a night certain for both sides. Overnights, events and trips away are planned a little further ahead, since a whole night or a journey leaves her diary.

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. She is given her fare personally, on the night, as soon as she is with you. 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.
