I saw Adele last week, and being relatively inexperienced, I was admittedly incredibly nervous.
I must say she is so warm, and is one of those people that is so charismatic that you can't help but feel special around her. She certainly puts you at ease quite quickly as she's a great conversationalist (amongst other things), and is truly a joy to speak with as she possesses a great sense of humour and is quite insightful about whatever topic you've chosen to address.
Ultimately, as others have noted, she's even more stunning in person than is reflected in her pictures (and she looks amazing in those as well). She also does everything she can to ensure you have a great time - and does it all effortlessly IMO. I'm not sure you could ask for more.
I think one of the most complimentary things I can say is that in spite of my nerve-induced awkwardness it was quite clear that she was feeling a little bad that I remained in that state throughout most of the session. She really genuinely wants you to have a tremendous experience - I think that's what everyone would hope for from a provider (that her priority is your enjoyment), and she provides that and then some. She certainly far exceeded my expectations. :)
