Joy of Languages (Italian)

Joy of Languages (Italian) is an Italian teaching channel with at least three different teachers. Polyglots will recognize Stefano, who also runs his own channel Lingua e Passione. Most of the videos are by Katie and / or Matteo.

Katie and Matteo also run the channel Easy Italian. Metatron Academy evaluated this channel. Katie sounds perfectly Italian according to him, indeed speaking with a northern accent as is plausible for the location (Milan). He elucidates that Matteo orginiates from Campania (as confirmed in his answer, he is Neapolitan).

A first video is Titled: One thing that'll make learning Italian much easier (Youtube link). Yet only the title is English.

The channel consists of beginner videos, where Katie speaks a lot of English and intermediate or advanced videos where only Italian is spoken (though generally at reduced speed)

Stefano joins in for advanced content as in following video: If you know these 12 words your Italian is amazing (YouTube link).

Don't worry, intermediate Italian speakers might not know a single one of those 12 words. Only two in my case, one of which due to my Belgian French.
