A bastion of quirky, laid-back charm, helped along by the story of Wilhelmina - she’s the fictional character seen in the sultry painting hanging in the cocktail bar. It provides a theme, and everywhere you will find Wilhelmina’s individually sourced ‘travelling treasures’ – we especially like Skippy the stuffed five-foot kangaroo in boxing gloves, and his nameless companion, the stuffed ginger cat in a dress.
   There’s no reception, you walk right into the cocktail parlour, the heart of the operation, a spacious hand-painted red room with wooden floors. To your left is the small bar serving well-crafted experimental cocktails, to the right, a huge marble fireplace and soft leather sofas. In the evenings it buzzes with a mixed bunch of smart businessmen and artsy types, and has a charming speak-easy atmosphere.
   The other three floors are given over to the 13 rooms. Each is individual and well considered, with colourful furnishings and a distinctive collection of original pieces, giving them a contemporary 50s feel. Our room, The Apartment, was huge and had a charming writing desk and antique trunk, charcoal walls and a Paul Smith-esque striped carpet. The bathroom was impressive, though the freestanding bath wasn't porcelain. Other rooms are smaller but continued the old-and-new blend, and had equally well-proportioned bathrooms, with welcome touches of colour.
   The Zetter Townhouse doesn’t have a restaurant, so if you want to eat well you should book at Club Zetter Wine Room & Kitchen in The Zetter, opposite. However, snacks are available in the cocktail bar, though eating at the smaller tables is awkward, and the modern street-food-style menu may not be to everyone’s taste.
