Not only have eons of high level politicians, diplomats, royalty and journalists used this is a temporary abode, it was a favourite among spies in the World and Cold Wars. Some A-Listers have taken entire floors of this palatial residence, attracted by its amenities (like bullet proof windows). And it has a most unsual ownership, having been gifted to the Swiss Confederation by the National Bank. Inside, is a gym with a sauna, cigar lounge, a club, a chic brasserie with an alfresco terrace and an open kitchen grill restaurant serving crossover dishes and bowls.
