Hong Kong Daily Press 1 June 1865. A long-winded name for a private hotel. Formerly the premises of the German Club.
The 1859 and 1865 maps at: https://www.hkmaps.hk/viewer.html show the Nullah and Headquarters House. Guessing the location is on the south side of Queen's Road adjoining the Nullah. Carl T Smith mentions in The German Speaking Community in Hong Kong (1846-1914) that the premises were below Headquarters House.
