Escorts W2: one postcode, seven stops, one desk

Paddington is the district page: the basin, Praed Street, Sussex Gardens and hotels including Hilton London Paddington. Paddington Station is the arrivals page, built around the Heathrow Express and a booking made before the train comes to a stop.

Lancaster Gate holds the tall hotels facing Kensington Gardens, Royal Lancaster London first among them. Hyde Park takes in the hotels on every side of the park, from the W2 terraces round to Park Lane in W1K.

Bayswater is squares, stucco and serviced flats between the park and Westbourne Grove. Queensway is the street that keeps its restaurants open late, with Hilton London Hyde Park at its southern end. Edgware Road carries the conference trade, anchored by the Hilton London Metropole.

Four neighbours share identical terms. Maida Vale, W9, starts at Little Venice. Notting Hill, W11, begins at the western end of Westbourne Grove. Holland Park, W11 and W14, is three Central line stops west of Lancaster Gate. Marble Arch, W1H, holds the corner where the Edgware Road meets Oxford Street.

One fare board covers every street in the postcode. The ladder climbs from £250 for sixty minutes through £400, £500 and £700 for the longer visits, reaches £900 for a four hour dinner and ends at £1,800 when she stays the ten hours of a full night. Messages are answered inside 10 to 15 minutes, and a companion normally reaches a W2 door inside the hour.

Three of them, Laura, Nora and Vanessa, live inside the postcode. The full lineup and the rates page cover the rest.
