The oldest concert room in Vienna, an oval frescoed hall with a cupola and thirty-five seats. Mozart lived and played music here in 1781. Today a string quartet or piano trio plays, Tuesday to Sunday, no singing, no ballet, no costumes.

Said honestly: the seating is tight, 59 to 69 euro is not cheap, and the entrance is hard to find (not the garage gateway). In return you sit two metres from the quartet. It is the most intimate musical evening in the city. mozarthaus.at.
