A couple dressed in traditional Catalan clothing, surrounded by animal musicians, are found on the lintel of the main door which leads into the entrance hall where a visitor is met with a message of welcome, "DEU VOS DO BON DIA Y BONA HORA” Literally, GOD WISHES YOU A GOOD DAY AND A GOOD HOUR paved in Roman mosaic. The dwelling takes up the whole floor and its distribution is based on that of Barcelona’s classic Eixample despite significant modifications which were introduced by Puig i Cadafalch, with the elimination of some partition walls and even some master walls, duly replaced by arches, to achieve more of a sense of spaciousness.
In the first bay, adjacent to the street, there are two bedrooms, that of the father (Antonio Amatller separated from his wife in 1877) and that of his daughter, with majestic doors featuring sculptural allegories dedicated, on the first one, to the collection of memorabilia gathered thanks to “l’Estalvi i a l’Intel•ligència” Saving and Intelligence, and on the second one, the virtues of a girl: “Laboriositat, Fidelitat i Feminitat.” Laboriousness, Loyalty and Femininity. In between the bedrooms is the sitting room, with the collection of archaeological glass in specially designed display cabinets, and the “work room”, places in which both of them could relax.
Following on from the bedrooms, in the direction of the inner courtyard, are the corresponding dressing rooms and bathrooms which also lead onto the corridors that connect with the other side of the flat. Featuring “aresta” ceramic wainscots similar to those in the lobby, and corners made of pink marble from Buixcarró, receiving the natural light from the interior patios through large stained glass windows and separated by a sequence of diaphragm arches of Islamic inspiration to accentuate and better appreciate the space, they are flanked by the service’s rooms. Separated from said corridors by two stained glass screens, the chocolatier's office is located in the central point of the floor, from where he perfectly controls the life of the house.
At the bay on the inside of the block, preceded by a luxurious sink, is the dining room, warmed by an imposing fireplace with a wrought-iron chimney and a large sculpture portraying the overseas Colonies, the origin of cocoa, and under the generous gaze of a representation of “Abundance”, on the door to the adjoining room and the guest room. On the other side of the dining room and separated by three lobed arches, the “music room” presents a frieze with verses from “La Cançó del Mariner” The Song of the Sailor and the original version of Els Segadors. The scullery completes the service of this part of the flat, with its dumbwaiter that goes from the kitchen to the ground floor.
