Samanta, composed from lobby to lift

Samanta keeps a private list of the best hotel staircases in London, and she will show it to you if you ask nicely. Design hotels are her hobby: the Art Deco lobby of Claridge's, new rooms behind old facades, the great domed rotunda at Ten Trinity Square beside the Tower. She notices proportion, light and the way a marble floor holds the evening sun, and she notices people in the same composed, attentive way. Ask her for the finest lift in the West End and she will name it without hesitation.

Samanta stands 174 cm, slim, with dark brown hair falling long over one shoulder and brown eyes, and she dresses in sleek noir: black, fitted, a single statement earring. She is in her late twenties and has a magnetic stillness that draws attention without asking for it. She plays the violin, mostly Bach, mostly late, and is learning Italian verbs on the Tube, although every booking runs in English and she is honest about the verbs.

East is where her best evenings go. A drink at the Four Seasons at Ten Trinity Square, under the dome of a building that once ran the business of the Port of London, then dinner in the City and a walk past the Tower in the dark. She treats a business dinner like a well rehearsed quartet: everyone gets a part, nobody plays too loudly, and the host always sounds good. Back in Mayfair she likes a nightcap at Claridge's before the last lift of the night.

Samanta lives in Mayfair and travels happily to the City for dinner. She prefers everything settled by mid afternoon; send Henrietta the hotel, the restaurant if you have one, and the time.
