We stayed for one night in Antwerp. Had a friendly welcoming from Jay and gave us a map where to go. The check-in and check-out times where flexible which is great for not being in a rush. Great thing about the apartment is that you can park your car for free in the harbour area which is 15min walk. And the walking distance to the old part isn't far either. So Location wise it's perfect.
Apartment was a bit smelly. Shower is very huge including a bath. But the toilet is really small. You are really sitting with your knees against the door. But there is a bigger toiler on the main level.
