A nice, small house in Leuven. We lived here with 4 friends during last year, but in the summer only one of us is staying, so we have some open rooms and space! :)
It's a really cosy place, the room is on the top floor but very nice!
To go to the center you can just walk 5 - 10 minutes or even take the bus (not really necessary tho). The station of Leuven is also just 5 minutes by foot.
