The apartment looked pretty snazzy just going from the pictures on this site, but when I let myself in I was blown away. Old building, but this flat would not seem out of place as a Dubai penthouse.
Tom was incredibly helpful in responding to any questions I had. Due to a lack of brainpower, I had booked it for a day shy of what I really needed. Tom sorted it within half an hour.
The weather was filthy, but 10 minutes after turning the heating on, the place was warm as toast.
As to location. You'd be hard pressed to find somewhere better in Antwerp. Walking distance to everything.
The stairs are potentially lethal, but it's an old building.
I've stayed in dozens of AirBnBs. This is in the top five. Don't look around. Just book it.
