Could you please elaborate a little, to make your note more useful?

I see two possible mistakes in this area:
1) https://www.openstreetmap.org/node/3345940217 apparently comes from a former building.  It looks like it should be deleted.
2) UrbIS numerical imagery still shows odd housenumbers 95 to 109 along Rue de la Loi/Wetstraat despite there is no building there.  As long as we ignore those, this is fine.
