The early twenties end of the roster
Everybody on this site is an adult and over eighteen, and this band is simply the youngest end of the book. Six of the women here have their early twenties stated plainly on their own pages, and those six are the ones described below. The shortlist itself runs a little wider, because the middle of the twenties has to fall on one side of a line that is not really there.
That is the honest way to read any age band. It sorts a roster; it does not describe an evening. Her own page on the board carries the version to trust, and the desk will tell you the same thing if you ask it directly.

Hoxton Square, and the last to leave
Bianka is curvy at 165 cm, light brown hair gone gold at the ends, hazel eyes that turn green under a low lamp. An easy talker, which is a different thing from a constant one, and she asks good nosy questions and then listens properly to the answers. She cooks badly and with real enthusiasm and holds firm views on which market stall does the bread.
Beside the park, and always one more stop
Jasmin is petite at 160 cm, chestnut brown and straight, and walks the towpath at nine without looking over her shoulder. She is a natural organiser of other people's evenings and keeps checking that you are enjoying the thing she has just invented. She draws buildings, mostly badly, in a notebook she will not show you until about the third hour.
Spitalfields, and a memory for side streets
Lea is petite at 161 cm with auburn waves and hazel eyes, and takes the turnings off Brick Lane without checking any of them. She asks questions in threes and keeps the answers, which becomes obvious the second time you meet her. She never has a phone out at a table and treats that as manners rather than a rule she was handed.
The station end, and a head for heights
Luna is curvy at 171 cm with long dark auburn red hair and is easy to talk to inside ninety seconds. She likes high rooms and long views and is straightforwardly delighted by weather: fog over the towers, rain on a window forty floors up. Stacy is slim at 176 cm, near black brown, watchful before she is talkative, and back on the third of October.
Brushfield Street, restless in the best way
Roxi is curvy at 168 cm, black hair worn loose, with a posture that turns a plain dress into a decision. She is quick enough that a slow evening visibly costs her something, and honest about being warm, funny and slightly restless all at once. She knows the market traders by name and is taking dates from the ninth of October.
What the band is, and is not
A sorting aid. It carries no promise about temperament and no suggestion that younger is better, which would be a silly thing for a book like this one to imply. Several of the best evenings on this roster are booked from thirties and beyond, and the desk says so freely when asked.
Where these six also appear, and how to write
Two are on petite, three on curvaceous, one on raven haired and one on auburn and red. They take room calls and late nights more often than anything else on the book. Give booking a name, an address and an hour, and the answer comes back in writing. An hour is £250; the ladder is on rates.
Other shortlists
The trains stop. We do not.
One message with the date, the time and the postcode, and the rest of the night is arranged quietly, anywhere from Hoxton down to the basin at Limehouse.
