Once a booking is confirmed, the arrival window is forty to sixty minutes to a central Amsterdam address, and a pair of therapists keeps to it as closely as one.
Couples often ask whether booking two therapists means waiting longer. It does not. Anywhere central, expect the knock forty to sixty minutes after the booking is confirmed, and when two therapists are booked, both aim to be at the door inside that same stretch.
The window does not change with the neighbourhood. A room near Dam Square, a flat in De Pijp, a hotel over the water in Noord: each is quoted the identical window. It does not change with the hour either, so a booking confirmed at two in the morning is timed exactly as one confirmed at two in the afternoon. Hotels at Schiphol and around the airport sit outside this; they are by arrangement, with a deposit, and the journey time is agreed with the two of you before anything is fixed.
Forty minutes is about the length of a shared shower and a glass of wine. Couples who book from a restaurant table can usually settle the bill, walk back to the hotel and be ready with a few minutes spare. Use the time to clear a surface, dim a lamp, move the luggage off the second bed and have the balance ready. If one partner is still out, say so when you write, and a later start can be agreed rather than two therapists waiting in a lobby.
Two therapists rarely start from the same place. Each makes her own way, both aim for the same window, and the session begins once both are in the room. For a booking at a set later time, the window does not apply in the same way: the therapists aim for the hour you agreed.
