Which is safe and best place to stay in? (Brussels)

Hello,
We are shifting to brussels in may Protected content around 1 year or more. We are looking for a good apartment on rent, but we want it in a very good and safe area. good neighbourhood, closer to supermarkets and well connected to the city. We are not more of nightlife people, prefer simple routine and comfort at home. Can anyone pls suggest the right choice for us.
Thank you in advance:)
