Hitler sometimes used the Munich apartment for high-level diplomatic meetings. On September 25, 1937, he met there with Benito Mussolini when he was trying to get Mussolini to agree to his plan to annex Austria to Germany; the leaders agreed to a strengthening of their Axis pact. He also met with British Prime Minister Neville Chamberlain in the apartment on September 30, 1938, following the signing of the four-power Munich Accords.
