The house was divided into four apartments that were assigned by drawing lots: an individual apartment (Daniel L.); one for two people (Laura F. and Javier); one for five (Laura S., Gemma, Mahme, Daniel R. and Pulpillo); and one for six (Kiko, Marusky, Greta, Kiran, Miriam and Naiala). In this edition the competitors were able to use the immediate nomination, meaning that competitors could nominate at any time of the day and were given six points to distribute as they wished. A competitor could use immediate nomination only once, with no other competitor aware that they had used it. If the competitors did not manage to pass a test they could obtain the budget by winning a "Panic Room" challenge.
