Do you live near Notre-Dame-de-Laeken?

You can answer all those questions yourself by checking things out personally. Doesn't your future living situation deserve personal attention and effort? Go to the property at different times of day to experience the A12 traffic. Ask in the café by the church if the bells are a nuisance. Drive around the neighborhood and discover what it has to offer.
Someone else's feelings about things will never be as useful as your own, and where one lives is extremely important to one's satisfaction
