First of all Willem is a very nice and witty guy. He's very fast in his communication and made our stay as easy as possible. The apartment is nice, it's perhaps not the best in town but fairly priced and very nicely situated in the middle of Antwerp. The beds in the bedroom were very nice, but the additional 'beds' in the living room weren't superb, again relative to the price it is decent enough, but for a longer stay with a big group (~5-6) you might want something more comfortable. The last point of critique is about the bathroom, even though the bathroom was nice and clean, the showerhead holder was broken so you had to hold the head while showering, which was rather inconvenient.
All in all its mainly the location and the fair price that make this apartment attractive, and Willem is an ideal and easygoing host. Thank you Willem!
