I've always been inspired by old industrial buildings like factories, but unfortunately such buildings have become rather rare in the Netherlands. At the moment you can still find some of the remains of the old harbour of Amsterdam called the ‘NDSM werf’ on the other side of the river ‘IJ,’ but this area seems to be in transition as well. For the time being the NDSM werf is a creative place where a lot of activities are taking place. The best part for me is the 'Y-helling' to enjoy the (modest) skyline of Amsterdam and to write graffiti.
Hannekes Boom is one of the nicest waterfront café in Amsterdam to have a beer when it's sunny. Close to Central Station, the place isn't crowded by tourists, but you need to be there early to get a seat.
Her I enjoy the quit and concentrated atmosphere. I go to the library if I need some new input or just want to work somewhere else than in my studio. You can also just go there to relax at one of the beautiful spots in the building. Or have some food at the top floor with a beautiful view over Amsterdam.
Not a big fan of zoos and animals behind cages, but if you can spot Flamingos in the east-centre of Amsterdam, then count me in <3 ! You can actually see them while riding the bike on Plantage Middenlaan, quite a beautiful scene.
Note: De Plantage next to zoo is quite cool cafe/restaurant, with a mix of vintage style and industrial elements of the old buildings of Artis. Great atmosphere, and ideal for a more sophisticated outing.
