I’m standing in milady’s boudoir, a room which would have delighted Liberace. Here, nothing is de trop and everything is geared towards lavish indulgence. Two enormous freestanding baths face the window, giving exhibitionists a heaven-sent opportunity to disport in the altogether. The upstairs bed could comfortably accommodate four adults. Portraits of Ada Lovelace — who has given her name to the suite — festoon the staircase, and a half bottle of Taittinger champagne begs ‘Drink me’ in an ice bucket.
