Between 1997 and 1998 Daciano da Costa would intervene in a ground floor section previously occupied with bureaucratic services and that it was decided to recover for representative functions. In areas adjacent to the main lobby, an area for public reception and an exhibition gallery was created: in the background, a new room for public sessions and their lost steps. Thus, one can still see today the recovery of the interiors and the design of furniture made by Daciano da Costa: public sitting room, support office, entrance, multipurpose room, Passos Perdidos and public reception (ground floor), office furniture of the president and vice president.

Os paradigmas da arquitectura brasileira do Movimento Moderno e a memoria das vanguardas do inicio do século – neoplasticistas e suprematistas, a Bauhaus e Le Corbusier – têm uma presença muito evidente no conjunto do hotel.

Embora tenha sofrido alterações ainda se mantiveram algums quartos com a arquitectura de interiores original: restaurante, grill, cafetaria, casino sala de jogos, cineteatro.
