These other reviews are spot on; we had a great time in Gwen's studio as well. It's nice, clean and well equipped. The TV with Chromecast is great for Netflix after a day of shopping or exploring. Antwerp Central station and the city center are a 15 to 20 minute walk away, 10 of you take an electric scooter. ;) The Lidl supermarket one street over is very nice for fresh bread or pastries at breakfast. Book this airbnb, you will not regret it!
On top of the remarks in Antwin's review: open up windows for fresh air, there's no holder for the showerhead, and no bathroom door (so get comfortable using the toilet with your fellow traveler sitting in the adjacent bedroom). I would add that a full-size mirror would be a nice addition and to bring a sleeping eye mask if you're a light sleeper. The roof window tends to illuminate the room slightly during the night. But these things aren't dealbreakers, this studio is absolutely awesome! :)
