Salah Abdeslam, 26, is thought to have fled the scene after seven other attackers blew themselves up or were shot dead by police after killing 129 people.
"Two rooms were rented from November 12 for one week in an apartment hotel in Alfortville," a suburb southeast of Paris, police sources said.
Police were still trying to determine who stayed in the rooms.
"I heard police smash open the doors on Saturday night," said a woman staying in the rooms next to those that were rented out, speaking on condition of anonymity.
On Sunday, police raided another apartment in the gritty suburb of Bobigny which was rented on November 10 by Abdeslam's brother Brahim, who blew himself up in front of a bar.
Investigators have identified five of the attackers involved in the attacks on the Stade de France, a rock concert, bars and restaurants, leaving 129 dead and 352 injured.
