As I live nearby, Le Duplex was perfect for my parents to stay while visiting me. It was cosy, clean and outfitted with all modern amenities (great hot shower, bathroom, kitchen, heating, cable TV, good wifi, etc). The twisty stairs between the two floors were a bit much for them, but wouldn't be a problem for younger guests. In general I can say that it's in a great area - 5 minutes from trendy Flagey square with its hip bars, resraurants, and weekend market. It's also 20 minutes from downtown Brussels or the EU district with lots of direct transportation connections. It's on a pleasant street in a nice, old, traditional Brussels house. Alexia was a friendly and responsive host. I wouldn't hesitate to recommend this flat to other guests in the future.
