With 24 hr licence to function as club, nights easily turn into days here. De school houses a coffee and a restaurant place, you can literally enter Friday and leave Sunday. :0
Quite in weekdays with great coffee, atmosphere and natural light
Unfortunately it’s not in Amsterdam but De Pont, museum of contemporary art is worth the 1,5 hour trip with the train. The building itself is beautiful, it’s a former wool mill but also there collection is worth seeing!
