I recommend Els's rooftop apartment. Communication with Els was straightforward. She always answered my questions quickly. The check-in and the check-out were flexible, which is nice. The condo was clean and organized. We stayed there in a group of 5, and it fits nicely. The location was good too (around 10 min walking from the Antwerp station). There was enough kitchen appliance (cutlery, plates, pans, coffee machine).
