Just for the sheer luxury of The Levin's in-room mini bar, we had to include it in this list. Each of the 12 rooms of the boutique hotel features an in-room Champagne mini bar. A range of different bottles of Champagne are on offer to guests, as well as the ingredients and recipes to create your very own Champagne cocktail. 

The rooms also include a library of Penguin classic novels; so pop the cork and curl up with a great read after a day of hitting the nearby designer shops of exclusive Knightsbridge for a truly luxury experience.
