San Francisco's Fairmont Hotel, the "White House of the West"

• Nearly every U.S. president alive has stayed at the hotel since it opened in 1907, according to Vanity Fair.
• It also hosted the signing of the UN Charter in 1950 and singer Tony Bennett's first performance of "I Left My Heart in San Francisco."

Of note: Julia Morgan, the first woman to receive an architect's license in California, reconstructed the hotel after the 1906 earthquake.
