Brielle is based in the Centrum, close to the squares where many nights out finish and a short walk from the hotels around them. French, Dutch and English are the languages she works in, so a guest can reply in whichever comes easily after a long dinner. At twenty-two she is direct about her limits and states them once, at the start. She tends to offer four-hand sessions and sensual work, and she decides in the room what the time will include. A guest who is back, showered and clear-headed has already done everything she asks. A four-hand booking with her needs a room where three adults can move around the bed without stepping over a suitcase. Every figure on her page doubles once a second therapist joins, and half of that doubled total is sent ahead at any length, whatever the hour or the date. Because the two of them agree beforehand who leads and who follows, it is worth arranging earlier in the evening rather than from the last bar of the night.

Brielle decides which bookings she takes and may decline any of them; she sets the limits for what a session includes, says what they are, and may end a visit at any point, as the terms set out.
