Great little flat, well equipped, comfortable and spotless. Sarah is very welcoming and provides all necessary instructions.
Easy access to public transport to get around (only a few minutes to Gare du Midi on tram 81). The Parvis Saint Gilles, where you can find various restaurants and bars, is a short walk away.
Just note that the main bedroom can get a bit noisy because it is on the street side with no sound insulation so maybe not recommended for light sleepers.
Apart from that, highly recommended base to explore Brussels!
