"The Marquis de Sers, it seems, was a country gentleman in need of a Parisian second home — he commissioned this classic four-story mansion just off the Champs Elysées in 1880, and in the intervening hundred-plus years it went on to become first a rather conventional hotel (the Queen Elizabeth) and now, a refreshingly unconventional one: the Hôtel de Sers." - Tablet Hotels
