It happened at a house in Maryville Court shortly after midnight.
Two masked men, one carrying a gun and the other a crowbar, forced their way into a property and demanded cash.
There were no reports of any physical injuries but police said the women had been left shaken by the ordeal.
The robbers fled in a small grey car with two mobile phones and a purse containing a small sum of money.
