"5to Piso" is mainly driven by piano and strings. Exceptions are "La Bailarina Vecina", crafted with pure orchestral arrangements; and "Ni Tú Ni Yo", a Ranchera style song featuring Paquita la del Barrio. The album also includes a song called "Que Nadie Vea", in which the artist sings about homosexuality. On "5to Piso", Arjona commented that he tried to recoup the freshness of his first albums, saying that he "tried to reconcile a little with the Ricardo Arjona from the first albums to let out some of that freshness that makes so good to the songs." "Poquita Ropa" offered a drastic change in which Arjona minimized the number of instruments. The result was a set of a cappella performances. Arjona commented about this album that "music and women look better with little clothes." Production was handled by Arjona and Dan Warner, who also worked with Shakira, Celine Dion and Christina Aguilera. Birchmeier gave the album a somewhat positive review, saying that it was a "stripped-down acoustic effort", considering it "impressive". He also commented that "Poquita Ropa" "finds Arjona at his most naked, backed by spare arrangements of acoustic guitar, piano, and Hammond B-3 along with occasional touches of strings, woodwinds, and chorus vocals."
