Hello and bonjour

Please, does anyone know if there is any internet-cafées open 24 hours (or during the night) in Brussels? Anywhere in Brussels accessible with the metro or bus would be fine. I've tried to Google, but no luck...

And this is actually sort of an emergency; I'm stuck in Brussels for 9 hours from midnight till 09 in the morning in-between flights and I can't afford even a cheap hotel (unless they cost less than 30 euros...)
I will be very VERY grateful for help... I'm a young woman and it's my first time in Belgium. Thank you so much in advance! :-)

There are a number of internet cafes listed in the directory here on AngloInfo, some of which are open all night, however the airport has a communications centre where you can access the internet. This link will give you more information. http://www.brusselsairport.be/en/passngr/services/internet_telephony/
If you have your own laptop then you can use WiFi in most areas of the airport.

Mc Donalds offer free Wi-Fi. That's often where I head!
