When there are two adverb phrases of same kind, it is recommended to put the more descriptive one in the front.
But this people used and in between those adverb phrases.
My room was in the ship and on the 5th floor.
To me, this and seemed redundant to me. Since "in the ship" and "on the 5th floor" are adverb phrases (or are those complements) that modify "was", a to be verb, I thought it better to omit the word and.
My room was in the ship on the 5th floor.
But it sounds a little unatural. Is my sentence grammatically wrong? And if yes, why is that?
