Check-in went smoothly and Naoufel was very responsive about early check-in as well. The apartment is near the metro, train, and Montmartre, but it is in an interesting neighborhood... We were a group of 5 girls in our 20s and at points walking at night made us feel uncomfortable. I would not walk alone. Other than that, the apartment was clean and very spacious. It was a good place to stay for the weekend in Paris.
