Anne and her family are absolutely wonderful hosts. Their home was my first stop in Belgium, and they really went out of their way to make sure I felt comfortable. Breakfast was delicious, and if you're lucky enough to join the family for dinner, Anne cooks amazing Belgian (and even Spanish!) food. Going way beyond the call of hosting duty, Anne and Criso arranged to deliver my very large suitcase to my next stop. This is an incredibly gracious and kind family, and I felt very fortunate to have the opportunity to stay with them.
In terms of the room itself, it's very bright and homey. There's a small balcony overlooking the neighborhood, and there's just enough space for one person. Though there is internet, the signal is stronger from the kitchen, so if you plan to do a lot of work online, you may need to work outside the room. The decoration in Anne's home really adds to the nice atmosphere. The proximity to the metro line is also a definite plus, and the entire area of Saint-Gilles has such an artsy, easygoing vibe--it's a nice refuge from Brussels city center.
This would be my number one choice place to stay for the next time I go to Brussels.
