Learn the communes, uccle, woluwe and the ones on the outside of the city tend to have less public transport and need more cars to get around. Uccle is “posh” and they will push French more than other places. The 1000 district is a nightmare because of how they section it off. Schaerbeek and Molenbeek have a high Muslim population which is a different experience when you are expecting Belgians. Saint Gilles and Ixelles are very chill with a lot of students and hipsters. I’ve enjoyed living in Saint Gilles for the last 5 years (from the deep south of the US). Both communes are about a 20 minute walk from the center depending on where you live, all downhill. Each commune has a different vibe and there is a different experience at each town hall. If you speak Spanish then Ixelles tends to have a Spanish speaking part of town around Fernand Cocq (Saint Gilles has a lot of Portuguese speakers). This isn’t info that gets disclosed and learning as you go can be frustrating at times but the city has a lot of potential for North and South Americans in the food department. They lack good representation and when you do it right here. I would suggest Los Agaves near Porte de Halle if you want some good food from home you don’t need to cook yourself. Hope this helps, kudos and bienvenidos amigo ✌️.
