This was recommended to me as a good work cafe, and it is to an extent. If you can bear the rest of the non working clientele in the cafe. A lot of them are obnoxious and loud, w/o consideration for other people. Especially around 14-16:00 h since it is lunch time in Netherlands in that period. It's not hard to concentrate if you are used to working with headphones, but having calls is really hard. As a cafe this is a good and cosy place, but as a place to work, I would not recommend it. If you need some peace and quiet you'd better be off somewhere else. Also the coffee is so-so, and overpriced.
