BOBIGNY, France — Three days before the attacks that ripped through Paris, Djazira Boulanger handed the keys to her row house, across the street from a kindergarten, to a guest who had booked it over the website Homelidays.com. His name was Brahim Abdeslam.
She didn’t know that Mr. Abdeslam was a central figure in plotting the deadly assault. As Ms. Boulanger tended to her two young children at home, authorities say Mr. Abdeslam and a band of cohorts were down the street preparing weapons for an assault on the Stade de France and Paris’s nightlife district.
“Did I suspect something was wrong? Not at all,” Ms. Boulanger said.
A day after he checked in, Mr. Abdeslam’s younger brother, Salah, pulled up to the roadside hotel Appart’City on the southern outskirts of Paris, according to staff, to claim reservations he made on Booking.com — also under his own name. The rooms were for another set of gunmen in the attacks: those assigned to mow down spectators inside the Bataclan concert hall.
