i have a very light apartment close to the station of Antwerp. it's located on the top floor of a 5 story building on the plantin moretuslei. The area is full of diverse people living here, there are a lot of bars and restaurants, even the city park is in the neighborhood. The city center is accessible by metro, bike, or on foot (20min).
I have only have one bedroom you can also use as a second room, but you will have to sleep on a 2 person blow-up matras.
Have a nice stay,
