In 1858 Louisa Willet-Holthuysen donated the house to the city of Amsterdam in order to make it a museum. The building's gardens is one of its greatest attributes, and includes all types of historical plants and pots.
Inside the residential building, which today is used as a museum, you can see house appliances and art that used to belong to Abraham and Louisa Willet-Holthuysen. Among them are items like: silverware, plates and furniture decorated with English gold. On the first floor you can see the kitchen and garden, on the second floor the living rooms, and on the third floor the bedrooms. Everything has been exactly replicated. The walls of the apartment display paintings by Jacob de Wit, and the rest of the space is taken up by porcelain and silver ornaments.
