Bottom line up front: we would stay again.
Charlotte's apartment is beautifully furnished, and includes a kitchen, living area, restroom, and a loft bedroom in a studio space on the top floor. It looks great and the view out the back windows is great as well. It is up quite a lot of stairs, so be aware of that.
The location of this AirBnB is prime. There is lots to see and do (including many things in the Antwerp city card) within 15 walking minutes. It is also right on a tram line that makes getting to other parts of the city fairly simple.
We had no issues with the space or with the host. It was a great stay.
