I thought I heard that there was construction near Brussels Central Station. If there is, can one still easily walk to the NH Brussels Grand Place Arenberg hotel?
AFAIK, the construction project is a rebuild of the Gare Centrale Metro station, not the train station. That project does not seem to effect the walking route to the NH Arenberg.
