Nancy, 30, sunny company in Oud-Zuid

People notice the ease before anything else. Nancy walks into a lobby without any visible calculation, greets the concierge like a person rather than an obstacle, and has the whole first awkward five minutes dealt with before you have sat down. At 30 that is craft rather than luck. Sunny and easygoing is the file description, and both words hold up under the least glamorous conditions, a delayed arrival, a cancelled restaurant, a plan that has changed twice since lunch.

Details on record: 170 centimetres, curvy, long golden blonde hair, blue eyes, English. Golden-hour beach glamour is the description she supplies, and the four images, taken in garden daylight and at dusk, make the point without needing captions. The energy in them is genuine; she is the most physically restless woman on this board and the least fussy.

Swimming is the daily fixture, early and unglamorous, which is where the calm under pressure comes from, and Violetta keeps the same routine. Road trips are the holiday habit, long drives with a vague destination, which tells you most of what you need to know about her tolerance for a changed plan. Sushi is the third and simplest pleasure, and Thea will also choose a Japanese table over anything else available.

Oud-Zuid is where she is based, park at one end of the day and museum quarter at the other, with the ring a few minutes off and the airport an uncomplicated drive. Daytime bookings suit her particularly well, a long lunch, an afternoon that drifts, an evening that begins while it is still light. Nothing about arranging her is complicated, and nothing about the arrangement changes after it is confirmed. Give the desk a window rather than a precise minute and she will still tell you the precise minute.
