A WhatsApp booking is a reservation requested, accepted and recorded in a written thread with the office, whose reply usually lands within ten minutes, night or day.
Hotels confirm a reservation in writing, and so does the house. There is no switchboard and no call to take in a room where a colleague might overhear; the reservation is requested and accepted by message. WhatsApp carries most of it, and Telegram serves equally well for a guest who prefers it. The booking line is shown on the booking page.
A short message does the work. The office needs a neighbourhood, a rung from the ladder and a starting time; a therapist's name, a technique or a second therapist may be added. The hotel's name can wait, and the room number is given near the close of the exchange. An answer usually comes within ten minutes, whatever the hour, saying who is free and what the reservation costs.
When the office accepts, it says so in the thread. Where a deposit applies, its amount is stated in that same message, and instructions for paying it are sent in that conversation and nowhere else. They never precede acceptance and never come from a third party. Any account or number that asks for money in the house's name is an impostor and should go unpaid.
Hotel evenings run on precise small facts: a tower with a separate residents' entrance, a room on a mezzanine, a suite whose door lies round a corner from the lift. Written down, they cannot be misheard. The thread also becomes the guest's own copy of what was agreed, from length and fee to the half sent ahead and the half still owed, held privately on a phone rather than on a hotel folio or in a corporate inbox.
The office asks nothing about the purpose of a stay, and a guest may keep the exchange as brief as courtesy allows. A sample request appears in the guide on booking for a hotel stay, and the arrival window opens the moment the thread confirms.
