El Mundo had a couple articles about the visit. They are long so I won't translate them completely, but a few interesting anecdotes/comments.
When asked if she missed being a journalist, Letizia said she didn't miss it, but she did have very fond memories of being a journalist, and that she still has the journalist's eye and interest to be always on top of what's going on. Felipe then joked that she "interviews me daily". He also said, now seriously, that because of her he doesn't feel as precautious with journalists. They did acknowledge, nonetheless, that they do sometimes feel accosted by the media and get particularly upset with some of the "both triffling and libelous" things said in some media outlets.
They must of asked her something about her role or something, they didn't really say what she was responding to, but she said that she feels her main responsibility, since Felipe will be King, is to be his support. That she wants to be useful to the State and wants for the Spanish people to be pleased with her actions. With all the preganancy/not pregnant rumours she must have felt compelled to also say "we will have children."
The reporter said that while they (the Royal House) had certainly taught her protocol, they had thankfully not sufficated her naturalness. He describes her as having "transparent" hands, almost like those of a Dolorosa statue (the agrieved Virgin Mary) and a neck like a white iris.
Then he mentions their circumspect, careful remarks regarding some political stuff that unless you care about Spainish politics I won't bother with.
The best line: "They have condemned her to be Queen one day." Apparently the author doesn't think it's a bit of a prize to be part of the monarchy.
