If you want to be in the heart of Brussels, walkable to EVERYTHING including the train to get you to the airport, or wonderful Ghent and Bruges - stay here.
The apartment is very modern and has an incredible view of the spire of City Hall, which is really magnificent in the evening. All appliances and paint are brand new, the place is sparkling.
As I said everything that you want to do in the city is walkable from Jon & Ceca's Place. You can have great food, history and of course beer within a mile of the home.
The only downside (but something you almost always run into in Europe) is you have to scale many flights of stairs to get to the apartment, and they are narrow and windy. It was not an issue for me as a younger man, but could see it as an issue for an older couple or person - especially with bringing your bag up.
Overall - I could not recommend this place more, if you are going to Brussels it is the best deal in town!
