My friends and I stayed at Sam's place for half a week and it was one of the most relaxing stops on our mini eurotrip. His place was exactly as he described, very close to the metro and gare du Nord! It was very small, but super cosy and comfortable. His friend Arnaud was there to greet us upon arrival and was very welcoming and helpful! Sam also had left a list behind of food ideas around the area and helpful tips. It was about a 10 min walk to Sacre Coeur! And whilst he was on the top floor, thus the great view!! I finally understood how French women don't get fat.. They take the stairs!
