Cowshed Spa Tucked away from the hustle and bustle of Carnaby Street is the Cowshed Spa. This chain is part of the Soho House group, and it shows in the interiors — think mood lighting and the world's most comfortable sofas. Stepping through the doors of the salon, one breathes a sigh of relief as the stresses of the fashion calendar fade away. Plus, there is free Wi-Fi, so you can still catch up on emails with relative ease. Cowshed Spa, 31 Fouberts Place, London, W1F 7QG.
