Nineteen letters to the desk, and Bella's replies

Four things: which day, what time, how long, and the hotel or street. Adding a name from The Women helps but is optional. Hold the room number back until she confirms, and leave out anything beyond time and company, because nothing else is ever part of a booking.

Sixty minutes, from £400, with ninety minutes at £600 the next step up. There are no half hour slots, since a rushed half hour suits nobody. If you are unsure, an hour in a hotel bar is a graceful way to begin, and it can always be lengthened on the night.

Certainly. Lunch in a Mayfair dining room, an afternoon on Bond Street or tea before an evening flight all run on the same price list as a night out. Daytime plans are simply easier to arrange with a little notice.

Of course, and many guests do. Chats are cleared after each booking, so tell Bella her name and the month you met; she checks the diary and, if your companion is free, the evening runs exactly as before.

Not at all. Every hotel sets its own house rules, and your companion follows them like any guest meeting a friend. Tell Bella, and your companion will simply ask for you by name at the desk, or meet you in the bar first.

Yes, and in W1 it is almost a tradition. The Connaught Bar, the Promenade at The Dorchester and the Donovan Bar at Brown's all make easy meeting points. Tell Bella which you prefer and your companion will find you there.

Everywhere in central London. The five pages In Your Area cover W1 in detail, but Marylebone, St James's, Knightsbridge, Chelsea, the City and Canary Wharf all lie inside the two central fare zones, so reaching you adds nothing to the figure. Further out, Bella quotes the taxi before you agree.

Two. She can meet you at a Heathrow hotel, booked for three hours or more with her travel counted inside them, or you can ride the Elizabeth line into town and meet her at your W1 hotel, where the usual lengths apply. The second is often quicker than it sounds.

Whatever feels comfortable. She uses the first name you give Bella and goes by the name on her profile. Surnames stay out of the conversation unless you choose otherwise.

For wherever the evening is going. Tell Bella about the venue, black tie for a gala, sharp for a cocktail bar, relaxed for supper in the suite, and she dresses to match. Given no brief, she picks something polished enough for any lobby in Mayfair.

Only the one your venue sets. A jacket is rarely wrong in a Mayfair dining room, and for supper in the suite you can come exactly as you are. Mention the plan to Bella and your companion will pitch her own look to sit comfortably beside yours.

There is no list, no database and no marketing. Your number stays in the chat while the booking is live, the conversation is cleared once it is over, and you may delete your side whenever you like. The privacy notice explains the rest.

In a word, company. Fees are for time and companionship only, so the figure covers her presence for the hours booked and nothing else; no other thing is offered, suggested or sold on any page, and a request for one ends the booking at once. The rest is simply good company, at whatever pace you set.

Not in the slightest. The figure Bella confirms is complete, and nobody in the line-up is waiting for more. If an evening was especially good, say so in the chat; Bella makes sure the compliment reaches her.

Weekends are priced on request because no two are alike. Send Bella the dates, the destination and a rough outline of each day, and she returns one all-in figure in writing before anything is held.

Her profile shows Available today or the date she returns, and Bella confirms with her personally before putting her name forward. If a reply says she is free, that is because she has said so herself. Profiles are refreshed whenever a companion changes her plans.

Yes. Her return date is printed on her profile, and Bella can pencil you in for that week. If you would rather not wait, tell Bella what drew you to her cover and she will propose a woman with the same kind of charm who is free sooner.

Then it stops there. Your companion can call time the moment an evening feels unsafe or disrespectful, and you are just as free to end it early. Mutual good manners keep this rare, and the terms spell out conduct in full.

Check where it came from. Bella uses only the two accounts behind the buttons on this site and keeps every exchange inside the chat your booking started in. Requests for passport photos, a so-called release fee or insurance of any kind are the signature of an imitator, so stop replying and come back through these pages.
