Hi
I'm not sure if this will be of any use for you but the Prince Felipe was actually moving to a new house before getting married with Letizia. The house was newly built within the Zarzuela area, it is within walking distance from it, and at the time (around the wedding time) there were some details about the house published. Some of them refer to the bedroom area, and some were general about the house. The source for this is the Spanish newspaper "El Mundo"
Graphic
On top there is a small reproduction of the palace, and the bottom of the graphic there is a small reproduction of the bedroom area.
I'll try to translate some of the details that go along with the picture describing it:
It has a swiming pool of 180m square, a dressing area (vestuarios) next to it.
"Buhardilla" means attic,and "terraza" means big balcony.
"Primera planta: 5 dormitorios, 4 vestidores, 3 salas de estar, 5 baños, 1 aseo, 1 oficina, 1 cuarto de servicio, 2 despachos y 1 terraza" This will be translated as " First floor: 5 bedrooms, 4 dressing rooms, 3 sitting rooms, 5 bathrooms, 1 toilet, 1 office, 1 room for the staff, 2 more private offices and 1 big balcony.
"Aparcamiento cubierto" enclosed parking. "Entrada Principal" main entrance.
"Sotano: 5 dormitorios, 4 cuartos del servicio, 4 baños, 1 aseo, 1 cocina, 1 office (I don´t really know what this word in Spanish means, so the translation might be wrong), 2 vestuarios, 1 muelle de carga, 1 cava, 1 despensa, 1 salon comedor, 3 ascensores, 2 salas de maquinas."
Basement: 5 bedrooms, 4 staff rooms, 4 bathrooms, 1 toilet, 1 kitchen, 1 office*, 2 dressing rooms, 1 loading and unloading area, 1 cellar, 1 storage room (food), 1 sittingroom cum livingroom, 3 lifts, 2 machine rooms.
"Entresuelo: 2 salas de audiencia, 2 salas del consejo, 1 sala de espera, 1 dormitorio, 2 despachos, 4 aseos, 1 cuarto de servicio y 1 office*. 20 plazas de garage"
Groundfloor: 2 audiences rooms, 2 meetingrooms, 1 waiting room, 1 bedroom, 2 offices, 2 private offices, 4 toilets, 1 staff room, and 1 office*. 20 parking places.
"El dormitorio del Principe: Felipe de Borbon dispone dentro de su mansion de 1 dormitorio en la primera planta, con 1 vestidor, 1 baño y 1 sala de estar con chimenea. Esta parte de la casa tiene 110m cuadrados."
"The Prince´s bedroom: Felipe de Borbon has inside his mansion 1 bedroom in the first floor, with 1 dressing room, 1 bathroom, and 1 livingroom with a fireplace. This part of the house has 110 square metres."
The last words in spanish in the part of the graphic dedicated to the bedroom area are as follow (first spanish version and then english):
Vestidor is Dressingroom
Distribuidor is Hall
Dormitorio is Bedroom
Baño is Bathroom
Sala de estar is Sitting room
Chimenea is Fireplace
There is a note by the newspaper at the bottom saying that this is not an exact replica of the house and the private area of the Prince is not marked for security reasons
There is also an article that goes along with the graphic that I don´t know whether it is has already been posted in the forums or anyone has any special interest in it. If so let me know and I will bring it to the forum.
All this is very old stuff, from 2003 aprox., I hope this is like the stuff you were looking for.
