We had a brief yet very enjoyable stay at Denis's apartment. It's perfectly located for those attending concerts at the nearby Zenith - a short and pleasant walk. Importantly, it is very easy to reach from the main transport hubs (Gare du Nord and CDG airport). We regretted not being able to spend more time in this lovely neighbourhood of Paris, as it looks very much worth exploring. Denis himself was very accommodating to our tight schedule, and even drove us to the train station the following morning. His friend Gamal welcomed us to the apartment. Communication with both was flawless.
The apartment is cosy, clean and has everything one would need for a shorter stay. Thumbs up!
