It's really bad, but it's still my favourite site to book hotels. I can filter for all criterias that matter to me and have all my bookings in one place. And their hotline worked for me when something went wrong.
Luckily my brain can filter most of the dark patterns.
I do (did) use it too, but then book through the hotel's own website, unless the price difference is too big. I'm not going to oversubsidize some search engine.
