There is guy from Sweden who documented his HT in a great way.
It's 100% worth paying the couple of €'s (for sure less than a beer in Denmark) to access his patreon for 1 month to watch the whole behind the scenes series. Insightful and pretty god dam funny. I found it funny that he did a lot of stuff 'wrong' but still got a good result.
Not one of the top clinics that is mentioned here, but would be an easy flight for you.
A summary is here:
(edit - I see the video is removed? Must be a rule to prevent spam I guess. but to OP on YouTube look for Simon Nackborn.
edit 2 - Just saw 2 years after his video he now actually works for the clinic he got it at, as a patient advisor.
