Renaud's apartment was lovely - clean, brightly lit, and well-situated. The neighborhood is quiet and friendly, about a 30-minute walk from the city center and not too far from a metro stop if you don't want to walk (though we enjoyed the walk! Good way to explore the city).
Renaud was also extremely communicative throughout our stay, responding almost immediately to our questions, and recommending some really nice cafes and bars in the neighborhood. We had a wonderful NYE at a local bar he recommended!
Highly recommended if you're looking for a comfortable, easy stay in Brussels.
