A numbered dwelling once associated with Aulisa and the Laubero family. It is a private house rather than a public building.

Unidad 39 begins as a modest private residence tied to the Laubero family and the enigmatic Aulisa, serving as a quiet backdrop in the early volumes. Across the series, the dwelling transforms from a simple domestic space into a nexus of hidden identities and covert operations, its unassuming façade masking the growing web of secrets that unfold within its walls. By later books, the location becomes emblematic of the series’ themes of facelessness and reinvention, its history intertwined with the protagonists’ shifting allegiances and the ever-deepening mysteries of the world.
