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.
Banging my head against the ceiling on the first floor doesn’t stop me from drinking a coffee in café Latei at Nieuwmarkt. I love it here, especially on rainy days, which is most days in the Netherlands. This small cosy café filled with a thousand colours warms me up.
