Frederics house is right behind Sacré-Cœur, very close to many restaurants. It’s a small studio apartment, perfect for students or people who don’t mind living in small spaces and are very adjustable. I personally didn’t find any problem except once when the water stopped working in the apartment but later found out there was a problem with the whole building and not the apartment. Frederic was also kind enough to extend my stay, which was really sweet.
