No computer, no internet - no problem. There are lots of public places to get connected to the Internet in the Netherlands. Most libraries in Dutch towns and cities have internet access, prices can be as low as €1/hour. It is, however, difficult to find internet cafes in smaller towns. It’s more likely to find an internet cafe in cities such as Amsterdam, Rotterdam and Utrecht.
In Amsterdam, you can go to the Easyeverything internet cafe on Reguliersbreestraat.
Warning: Internet cafés are popular targets for thieves and pickpockets, particularly in the centre of large cities. Keep an eye on your valuables at all times.
