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.

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.
