Aberdeenshire , Scotland ( CNN ) The Scottish Highlands on a wintry morning in January made for an awe-inspiring interview setting . We traveled along narrow roads winding among snow-capped mountains , eventually arriving at Birkhall -- the Scottish home to Prince Charles and his wife , Camilla , Duchess of Cornwall . I had pitched for interviews with the couple several times over the years and finally Prince Charles accepted . I wanted to speak to them about their 10 years of marriage and their upcoming U.S. tour . The couple 's first tour as newlyweds was also to the United States , so it felt like an appropriate moment to take stock . When you reach the house , it strikes you as an idyllic royal hideaway . It has the sense of a castle but is welcoming like a farmhouse . It has a pinkish hue and green window frames that take in the stunning views . We went in the back entrance and were escorted through the house to the dining room at the front where we set things up . Rarely have cameras been allowed in , and never to this part of the house . As we were getting ready , an aide announced someone wanted to say hello . The Duchess of Cornwall appeared from around the corner , keen to welcome the crew . We spoke about what all Brits talk about -- the weather . Prince Charles opens up about love and life . She is not what you might expect when you meet her . She 's more charismatic , which is something I hope comes across in the CNN special , `` Spotlight : Charles and Camilla . '' Unfortunately she had declined our request to be interviewed . She 's never done one and does n't plan to . She wants the limelight to be on her husband . The Duchess of Cornwall had however allowed our cameras to get close enough to pick up sound during some of her public appearances . That would give viewers a greater sense of her character than they had had before . When Prince Charles arrived , he also insisted on meeting the crew , which was great but was also eating into our interview time . In the end , we had the full 20 minutes as planned . You can make your own judgements of the TV special , but I think we did manage to give you a good sense of him . He was comfortable enough to be himself . He was the same person on camera as off . Afterward , we walked through the house and into the garden for some additional shots . The Duchess of Cornwall joined us on the way and was worried I would be cold without a coat , but the coat was inaccessible and I did n't want to hold things up . You ca n't tell an awful lot about someone by spending just a morning with them , particularly as a journalist , but my impression was that they are close , connected and have fun . I then left them to take a stroll on their own with the crew , who captured some shots that I think have a small place in royal history -- a glimpse of a couple enjoying each other 's company in their private wilderness , before he ascends to the throne .
