Here are three adverbial phrases. The first is "covered in dust and webs." The phrase "waited beneath the stairs" is actually the predicate of the sentence, so don't count it as an adverbial phrase. The second adverbial phrase is "safely hidden." The third adverbial phrase is "under the mildewing books and tattered newspapers."
The answers are "When you ride in a 1967 car, the world just seems to move a little slower." And "There you are, waiting for the bad news, when a relative starts laughing loudly."
The sentence should be written like.
"Our holiday should of been relaxing, but it was very stressful."
