Sofie's apartment is a great place to stay with small children, offering child seats and safe bed, baby cot and all kind of facilities for them. The flat has plenty of light and is spacious and very pleasant to live in. Only drawback would be the bathroom, quite elementary compared to the rest of the apartment, and cleanliness which was not perfect (at least according to our standards). The apartment is well located and if you're a good walker every point of interest of the city can be reached on foot.
