Only a lucky few will possess a key to their own palatial domain, the Corinthia’s Royal Penthouse Suite, accessible by private elevator. Guests are welcomed by a Chinoiserie entrance which leads on to a Macassar ebony dining room, a swanky lounge and a private office area. Upstairs, beyond the spiral staircase, a further lounge, the bedrooms and a private spa room await. The real star, however, is the expansive outdoor terrace which might just have one of the best views in London – look out over the River Thames, St Paul’s Cathedral and the London Eye. Access to a personal butler (and driver) and an extensive private wine collection seal the deal.
