It might be one of the owners (Vincente Mas, Andreas Nowotnick) that lives here and they used this address for the warehouse behind this building in the past, but now have a bigger warehouse a few blocks away. According to their website they are now located at 
Insterburger Str. 41
28207 Bremen

Unfortunately, that address is not in our database and will require a #surveyme

Be sure to also map the nearby building with no hausnr (might be 34 Insterburger).
