WhatsApp booking means a couple arranges a session in writing, the office confirms in about ten minutes, and every later detail is agreed.
The house takes bookings in writing, on WhatsApp or on Telegram, rather than by call. For couples this has an advantage beyond convenience: both partners can read every message over one shoulder, and nothing is lost to a bad line in a noisy bar.
A couples booking needs a few more details than a solo one, and putting them in the opening message saves a round of questions. Say how many guests and how many therapists, and whether you want to be looked after together or in turn. Give the length, the time you want to start or "as soon as possible", the full address with floor or room, and the technique or therapists you have in mind. Say whether either of you has booked with the house before.
Expect a reply in roughly ten minutes. If it can accept, the reply confirms the booking, names the fee and, where a deposit applies, states the exact amount in the same message. The payment details for that deposit follow in the same thread, only after acceptance. Details from anyone else, or before the office has confirmed, should be ignored. Once the deposit clears, or straight away for the one arrangement paid wholly on arrival, the therapists set out.
Everything that changes stays in the thread: a new room number, a partner running late, a wish to extend by an hour. Keep the same thread open throughout the evening rather than starting a new one. Couples who book from two phones should choose one and stick to it; the shared booking entry explains why.
The writing does not replace care in what you ask for. Keep requests simple and respectful, and give an address the therapists can actually reach. How the exchange unfolds, message by message, is on the booking page.
