Slim. Cleanlines, tendifferent nights.

Karolina, 27, Jordaan: poised and discreet, opera, piano, architecture walks. Samanta, 27, Centrum: composed, violin, a notebook of new words, a critic of hotel lobbies. Margo, 31, Oud-Zuid: refined and mysterious, contemporary art and piano. Violetta, 30, Oud-Zuid: elegant, confident, a bone-dry sense of humour.

Four women for formal rooms. Sleek minimalist, sleek noir, vintage lounge, desert gold. Different wardrobes, same precision.

Liana, 28, Centrum: gentle and intuitive, a reader of French novels, a pilates habit, a balcony full of herbs. Patricia, 28, Jordaan: romantic, watercolours, film noir, secondhand bookshops. Lucy, 24, Jordaan: dreamy and tender, planets from a bridge at half past one.

This trio suits the overnight, where many hours of real time together reward someone gentle and unhurried.

Cindy, 26: cheerful and sporty, yoga, sailing and a camera. Vanessa, 25: sweet and curious, language lists and a bike in all weather. Stacy, 22: bold and spontaneous, street photos at three in the morning.

All three live in De Pijp, close to the late kitchens and the busy terraces. Good for nights that move from place to place and never quite sit still.

Several in this set are at their best in the quiet hours. A hotel bar that has emptied out, a pianist on the last number, a low table and two glasses. Margo will look for the piano. Samanta will study the light fittings. Liana will look at you and know whether you want to talk or just sit for a minute. Violetta will find the one funny thing about the room and point it out, very quietly. For a late hotel outcall that begins downstairs in the bar, this is the set to open.

Several favour structure and clean tailoring. Karolina and Samanta go black and cut close. Violetta wears gold and white ruffles as if a gala is always about to start. On the softer side, Patricia goes floral and linen, Lucy satin and silver, Vanessa understated coastal chic, Liana deep reds for candlelight.

Tell the desk the dress code. She handles the rest, from the shoes to the coat she will need for the walk back along the water.

Six of the ten are tall, from Patricia at 172 cm to Violetta at 178. Cindy is the one blonde. Karolina and Violetta have black hair, Patricia is auburn. Margo and Violetta sit in the 30 and over band.

Rates run from €180 per hour. An overnight, or a dinner that drifts past midnight, is on request, confirmed on WhatsApp, quietly and in advance. Pick a name, then book.
