Mozarthaus Vienna is the one flat Mozart rented in this city that still stands. He moved in one floor up in late September 1784 and stayed until the spring of 1787, longer than at any other address here. It had four rooms, two small cabinets and a kitchen, and the museum calls it the largest and most expensive home he ever rented. He wrote The Marriage of Figaro in it, which is why Vienna still calls the building the Figaro house.
He also finished here the last three of six string quartets he dedicated to Joseph Haydn, the older composer he called his dearest friend. What you walk into is bare. Nothing he owned survived, so the rooms hold period furniture that was never his and a modern copy of an early piano. Only the building itself is original, including plaster ceilings that were already old when he moved in. Two floors above are panels, screens and recordings about his Vienna, and chamber concerts are played in the vaulted cellar.
