Ward's apartment is so great, I recommend it very very VERY highly! It's honestly even better IRL than in the pictures, and super well-located // you're near all the best stuff to do and see, but chilling out at home is also really nice if you need a rest since it's really well-furnished and more than equipped for cooking etc. Ward is very friendly and communicative (and even had a Belgian beer waiting for me when I arrived), so you're in good hands // definitely would be my top pick on a revisit to Antwerp!
