The main suite which, with its three interconnected rooms, is like a shop window display onto Passeig de Grŕcia, with huge windows which let the light in. Gaudí created large oak doors with organic shapes into which are set panes of stained glass. These doors, as well as separating the three rooms, allow a single light-filled space to be created. The ceiling is wavy, in allusion to the sea. It features an ingenious whirlpool effect which Gaudí achieved using an esparto plaster filling and which evokes the power of the sea.
