I agree with
@Lionessarising about Jonna Jinton. She is wonderful to watch. Stunningly beautiful filming, and she has such a positive view on life.
I like Chloé Kian at times (even though I am older, I like her food and lifestyle content). But then there was some life drama: broke up with her long-term boyfriend and then in a blink of an eye was posting about jetting off to Mexico to get together with the supposed love of her life, who comes off as a total jerk in her vlogs, making cutting comments. Her viewers noticed and commented, so she closed the comments on those particular vlogs.
There is also this older couple that I recently started watching. Now, at first they may be off-putting until you get used to their style: slower paced, extremely calm. But then when you see their enthusiasm for all things Brisitsh, and how cute they can be, they become so endearing. Their names are Kirsten and Joerg. They are a German couple, both always fascinated with Britain, got an opportunity to move there for his work, and now spend their weekends touring castles and gardens, or baking, or renovating/decorating their Victorian home. I relate to them, being older myself, but mainly because I, too, have been long fascinated with Britain (traveled there twice over the course of my life and am so wanting to go again!). So I sort of live vicariously through them.
[ETA]: BTW, Kirsten sounds completely British (at least to my untrained ears). The reason is that she spent several years living in Egypt while she was a teen, and the British Council offered English classes, so she learned the language from British people, thus picking up their accents.
