Mathieu and Karolien's place is just as described : basic but comfortable and affordable, and a great value in terms of location near the lively Marnix Platz and very close to many of Antwerp's great attractions. We did not get to meet Mathieu but Karolien was pleasant and welcoming. The only area which could have made the experience better was communication, prior and during our stay. There was none, a fact I understood better when I saw how busy both parents were with their children. Not a big deal then, but I did miss being able to chat with the hosts, which is one of the nice aspects of the AirBnB experience. All in all a good place to stay if you decide to visit the great city of Antwerp !
