Prince William is "charm personified".
The 34-year-old royal – who has two children with wife Duchess Catherine – presented an MBE to consultant nurse Ann Scott from Northern Ireland and she was impressed by how down to earth he was.
She told Belfast Live: "The entire experience was fantastic; Prince William was very charming and informal and very much put you at your ease.
"He asked me about what it was like for people in Northern Ireland living with dementia and he also told me that he and Catherine both love Northern Ireland and were looking forward to come back again.
"I asked him about his children and he said they were at the age where they were into everything and bumping into everything and we just had a laugh about that.
"He was lovely, he was quite simply charm personified."
Meanwhile, William recently admitted he has "struggled" to adapt to being a married father of two, but insisted he adores his family situation.
He said: "It’s been quite a change for me personally. I’m very lucky in the support I have from Catherine, she’s an amazing mother and a fantastic wife.
"I’ve struggled at times. The alteration from being a single, independent man to going into marriage and then having children is life-changing.
"I adore my children very much, and I’ve learned a lot about myself and about family just from having my own children."
Speaking about his children, he called George "a right little rascal", adding, "he keeps me on my toes but he’s a sweet boy".
And when asked about Charlotte, he said: "Bearing in mind I haven’t had a sister, so having a daughter is a very different dynamic. So I’m learning about having a daughter, having a girl in the family."
