Verloren in Leiden: Luggage

I took ill while in Leiden and abandoned my 2 pieces of luggage on the street. I was on Moorsport bridge when I was fell ill and was subsequently hospitalized for a month in Amstelveen. I returned without my luggage to the US and only recognized yesterday that the Apple AirTags showed the location. I assume it is a repository for lost kuggage at Moorspad 10, 2312 Leiden. But that might be any business or apartment  at that street address. Can you assist me?
