Charlottes appartment is just as it is shown on the pictures and described by earlier comments! Charlotte is very kind, communicative and the appartment has lovely gedgets to feel comfortable. Eventhough situated in a calm area it is within walking distance to the historical center.
I would just recomend some houseshoes or thicker socks if you are planing to visit Anvers in the winter time as the concrete floor might be a little cold. But that is also an individual feeling.
I recomend staying at Charlottes place!
