The museum is housed in an old "senior citizens home", where Frans Hals himself may have lived for a while (he lived until age 86!), which by itself is stunning. The exhibition is shown in the building that sits around the large courtyard, so there is a natural flow in the viewing.
Apart from Frans Hals' works, there are quite a few others of fame and splendour!
Very interesting if you are keen on Golden Age art.
