Hello.
Similar to your other edits, what is the source of this information?

Also there are a couple of issues in your edit.
If you want to indicate that  POI is on a specific floor, OSM has a tag called addr:floor specifically intended for that.
addr:unit is intended for unit/suite/apartment/similar address elements.
Please see https://wiki.openstreetmap.org/wiki/Key:addr:* and https://wiki.openstreetmap.org/wiki/Key:addr:floor
