Great value and location in the old town of Antwerp, would stay again. Perfect for a big group but we were only two people. Comes with all the quirks of an old building (tiny staircase, hard to find the light switches...) but the view is lovely and it's a nice big open-plan space with comfy modern furniture.
As others have mentioned, the check-in process is a bit weird. Would be fine if that's what was clearly advertised, but they go out of their way to conceal that it is clearly run by a business (which did put me off a little on arrival). That being said, the service of the staff was super friendly and everything was smooth. If you can put up with the weirdness, the apartment was well worth it for the low price and location.
