Desván translates to "attic" in English. It's a charming and somewhat old-fashioned word that evokes a sense of hidden intimacy and secrecy.
In the song, Chayanne uses it in the line "Sube al desván" (Come up to the attic), suggesting a private, secluded place where lovers can escape the world and be together. This makes the word intriguing and adds a layer of romantic mystery to the lyrics.
"Sube al Desván" is Chayanne's intense declaration of an all-consuming, obsessive love. He casts himself as fire and darkness itself, promising to burn, mark and claim the person he loves completely, writing their name on every wall and never letting go.
The title line, "climb to the attic," is the song's secret refuge: a hidden, private space where the two of them can be together "when no one sees us," away from judgment or interruption. It turns a simple household space into a symbol for a love so intense it needs to hide from the world to survive.
