The 'Kas di pal'i maishi - Kunuku House' museum is located here.

Google has some information on it: https://goo.gl/maps/d3KJmfneFtL2. Trip advisor as well: https://www.tripadvisor.nl/Attraction_Review-g147278-d150357-Reviews-Kas_di_Pal_i_Maishi-Willemstad_Curacao.html (wrong location on the map there).

Unfortunately I forgot to take a picture of the sign with opening hours (etc.).
