The duration ladder is how this house prices its time, set by length, by whether one therapist or two attend, and by whether one guest or a couple is receiving.
There is no menu of named treatments with separate prices. There is a ladder of lengths, and four columns beside it: a guest alone with one therapist, a couple with one therapist, a guest alone with two, and a couple with two. A couple reading it needs only to decide how long and how many therapists, and the number follows.
The rungs are one hour, ninety minutes, two hours, three hours and an eight-hour overnight, and every rung short of the night is the hourly figure multiplied by the time it names. Each hour past three adds that hour again. This column covers the sequential arrangement, where one therapist sees each partner in turn: two hours gives an hour each, three hours gives ninety minutes each. A guest booking alone with one therapist reads half of every figure in the column, the night included.
Two therapists on the two of you cost double the shared hour, and the doubling holds at two hours and at three. Beyond three hours, each additional hour adds another pair hour. The overnight entry in this column is quoted as a block, and it comes to eight of those pair hours rather than less. The same pair booked for one guest, the four-hand shape, drops back to the shared hourly figure, with its own night beside it.
Technique does not change the figure, so nuru and a sensual session of the same length cost the same. Neither does the clock, so a booking at four in the morning is charged like one at four in the afternoon. Neither does the neighbourhood inside central Amsterdam. What does change it is the number of guests: a couple sharing one therapist pays twice what a guest alone pays, and a couple with a therapist each pays twice what four hands on one guest costs.
For most couples, halving the figure gives the amount settled ahead. Two therapists on the two of you for two hours send half of that two-hour total ahead; a couple's first booking of ninety minutes with one therapist sends half of a far smaller one. Only one shape escapes that halving, a returning client wanting one therapist for an hour or two on the same day, which is paid wholly on arrival; the deposit entry explains the rest.
The full ladder, laid out in all four columns, is printed inside every therapist's profile.
