Overall, we were happy with our stay here. Once we got to wander around and feel comfortable with the neighbourhood and streets (by day 2) we found it simple to walk everywhere, be it the city-centre, gare midi, or to other neighbourhoods. I think it's a great choice for a longer stay (we did 5 nights). If you are visiting brussels for a short stint then I might recommend staying closer to the tourist sections as St. Gilles was a bit of a walk.
The extra touches by Samantha that were much appreciated: the big bowl of coffee pods, nicely stocked kitchen, and the towel radiator in a well lit and clean bathroom.
A couple of memorable spots near Samantha's that we happened upon: the outdoor market off Chau. Waterloo toward Porte de Halle with amazing cheese trucks, rotisserie truck and fresh made waffles on the wkd; Moeder Lambic which i recommend to any beer lover as their draught and bottle selections are phenomenal!
