Mokhtar's place is great! We stayed there with 4 people so it was a little tight, but it had everything we needed. He was super helpful and always responded super quick to my messages! Everything was very clean. His place is located on an awesome little street full of restaurants and bars, there's plenty to do close by. Its only a 15 minute walk to Gare Du Nord and 5 minutes to the metro. I would come back in a heartbeat!
