TripAdvisor places The Willet-Holthuysen Museum at #59 of 239 attractions in Amsterdam, which sounds about fair.
It is satisfying to enter one of the beautiful canal houses, which are normally so tantalizingly out of reach, and the view onto the canal offers a new perspective.
This particular abode formally belonged to the Willet-Holthuysen whom, childless and wealthy, donated their house to the city upon Louisa’s demise in the 1895. It is disappointing to learn that much of the house is a recreation rather than a preservation, however.
If you have a museumkart, then this is well worth a visit, and is conveniently located on the Herengracht for a quick foray. Otherwise, the €8 entrance fee might smart, and could be better spent on an Amstel on the Amstel.
