Swiss US-Iran talks venue a playground of world leaders, movie stars

The uber-plush Burgenstock resort perched high above Switzerland's Lake Lucerne -- the dramatic setting for Sunday's US-Iran talks -- is well-accustomed to hosting world leaders, movie icons and peace negotiations.The luxurious hotel complex was proposed by Washington and Tehran, and their Pakistani and Qatari mediators, for the negotiations aimed at fleshing out their preliminary agreement on ending nearly four months of war.The tranquil and picturesque location is hard to access, with water on three sides, and is therefore easy to seal off for major events.
