2 week room/appartment rental

have a look in www.airbnb.be and put the criteria you require (date, location, budget etc). it is quite easy to use and set up a profile. there should be plenty of offers in that area.

also you can see the availability of a place by clicking on "calendar".

if you could also provide a contact mail i might know someone who's offering a room
