I stayed in this room for a month while looking for an apartment and I can really tell you: this is such a lovely place, really a rare finding. It's on the top floor of a house with private kitchen and bathroom. It's pretty much like a studio and I found it perfect even for a longer staying. Tasja is really a great host and has put a touch of style in the apartment design: you won't find many rooms like these on Airbnb. I got so many great advices from her on things to do, places to visit and of course practical stuff (like where to find supermarkets, public laundries, etc). Overall she was always available for any problems I had.
The apartment is in the student area (which is quite lively), not really far from the city center (though distances in Belgium are measured on cycling references) nor from the central train station. I would definitely recommend to stay in Tasja's place, you wouldn't regret it.
