20 in St. Ann's Quarter (Sankt Annæ Kvarter) owned by judge Henrik Ehlers.

Johane Marie Mathiesen, a 56-year-old widow and the owner of the property, resided on the ground floor with four of her children (aged 16 to 29) and a maid.

Guests included the Norwegian writer Knut Hamsun who stayed there under the name "postmaster Hansen from Oslo".

A suite in the hotel also housed members of several Russian noble families who had to flee Russia during the revolution.

The attic was converted into a full storey some time 1743 and 1746 and a fourth floor was added in the second half of the 1880s.
