What's wrong with the algorithm?

[lurento.com]

Is it possible that Google is penalising a specific page and in the same time it shows unrelated page in the search results?

"rent luxury car florence" shows https://lurento.com/city/munich/on the 2nd page (that's Munich, Germany) and in the same time completely ignores the related page https://lurento.com/city/florence/

How I can figure out if the specific page has been trashed and why?

Thanks,
Mike

Both of those pages have canonical tags that point to https://lurento.com/city/ which 404s out.... I would start there.

Thanks, I don't know how I missed it. I've fixed the tags, Google has crawled and reindexed the website twice, however still a mess - plus the specific page is going up on serp? Anything else I can do to help Google get it right?
