Leo's and Katrine's accomodation is warm and nice. I staied there in December and the room was warm and the bad was confortable. Bathroom and kitchen are on the third floor. In the kitchen there's an addictional guest so it's not possible to stay there early in the morning or at night after 10pm. The place is near the Atomium in a residencial area, so if you need to come back home at night you should consider the last train is around midnight and it would take about 50 mins walk from the city center.
