I highly recommend Alexander's place: it's clean, pretty and functional. We had everything we needed: towels, hair dryer, comfortable bed and even a bouquet of fresh flowers in our room. The view of the backyard full of plants is very pleasant. His place also has a kitchen, which we really didn't use, since the location of his place is perfectly close to all the cafes.
The bike rental station and the store are almost next to his place too.
Great experience that made our stay in beautiful Antwerp very pleasant.
Will stay there again.
