My sister and I stayed in Rebecca's apartment for a few days and cannot recommend it enough. The room is spacious, clean, comfortable, and not too hot as Rebecca provided a strong fan. You have your own bathroom with towels and the the living room has a balcony with a gorgeous view. By train, it's about 20 minutes away from most tourist attractions. You are also only a 10-15 minute walk from Sacre-Cour. Also, it is only a 10 minute walk from the Gare du Nord train station and Rebecca was extremely helpful with directions to the apartment. The host quickly replied to any questions we had which was very appreciated.
