I had a great one-night stay at Claudia's -- you couldn't find a nicer host, a truly warm and generous person. Fantastic area bordering the heart of Montmartre and very easy to get to from the Gare du Nord with a metro line right outside the apartment. The room is very comfortable, and everything was perfectly clean. Claudia's cat is also very friendly! More suited to a short stay as it's a very petite 1-bedroom apartment, but perfectly meets the needs of a night or two!
