Excellent accommodation. Right outside the Antwerp central station. We used the train a few times and it was great to be so close. There are plenty of restaurants near and supermarkets. Just beware that not many shops are open in Antwerp (generally Europe) on Sundays.
The flat is very spacious, very modern and enough amenities for a short stay in Antwerp. Even good for a long stay actually. It was surprising to see Netflix on TV, which was good. Bath towels were provided as well as little shampoo sachets and even toothbrushes.
