Geir-Ole, unfortunately some reviewers don't check that they are posting their reviews against the correct listing, even though it is clearly classified under Attractions using the category Mountains.
You can request the website be removed from the Mountain's listing page. If you click "Update attraction details", click "Provide correct address" and then delete the website URL and then submit, this will go off to TA staff to update the listing.
You can also request to move reviews from one listing to another, if they've been posted at the wrong place. Currently this is broken for attractions and restaurant reviews, as is being discussed on the Support forum tripadvisor.co.uk/ShowTopic-g1-i12105-k60922…
When this is fixed if you click "Problem with this review" then click "Review is posted to wrong location", click Yes at the next prompt and enter the right place. There is an auto-search feature which will bring up suggestions to choose from, or you can type freely.
When I look at the mountain reviews, none are for accommodation at the hotel - some are for the restaurant though. Really, a third listing needs to be created for the restaurant then the misplaced reviews can be moved there.
