Interesting apartment at the top of an old house in Brussels, on a street with lots of character -- ethnic diversity, small shops, students, a museum entrance -- close by the Parc Léopold, the Place Jourdan with its Sunday morning market, and several European institutions. Hosts very welcoming and helpful. We stayed 4 weeks, visiting family nearby. The stairs helped to keep us young. Also the hills -- it's not true that Belgium is all flat!
