In operation for almost 160 years, this renowned Belle Époque resort on the shores of Lake Geneva in Lausanne is steeped in important history and culture. The treaty that broke up the Ottoman Empire was signed here in 1923, and guests have included everyone from Charlie Chaplin and Gary Cooper to Rod Stewart and Nelson Mandela. From 2012 to 2014, the hotel received a nearly $30 million makeover, helmed by famed interior designer Pierre-Yves Rochon, which complemented the timeless elegance of all 168 rooms and suites with such luxuries as Murano glass chandeliers, expansive mirrors to bring the views indoors, and entertainment screens discreetly embedded in bathroom mirrors. There are four restaurants on the property, most notably the exquisite Anne-Sophie Pic, which has two Michelin stars. In the summer months, the hotel also serves dinner on its own turn-of-the-century, steam-powered paddleboat as it plies the waters of the lake. The state-of-the-art spa, offering a wide selection of restorative treatments, opens up onto the resort’s 10-acre park and includes separate saunas and hammans for men and women, a Jacuzzi, two heated pools (one indoor, one out), and two tennis courts.
