How specific does a search warrant need to be?

Several years ago my neighbor was arrested for conspiracy related to knowledge of narcotics being sold in the home. She has told me that when the police searched her home (a 3 family) the search warrant stated "3rd floor apt" and she resided on the second floor, they searche her apartment based on that warrant. Does she ahve any grounds to appeal this conviction? She ended up a/3 years probation.
