Nicholas was easily available leading up to and during our stay, but we never actually crossed paths as keys were left in a lockbox for us to pick up upon arrival. We found this incredibly convenient, as our train was slightly delayed and we did not feel guilty putting someone out as they waited. It also made for a smooth departure. The apartment itself is wonderful and almost like a hotel room, with every amenity imaginable and one of the best showers I have ever had the pleasure of using. The location is also fantastic--we walked absolutely everywhere during our visit and never felt inconvenienced or like we had wandered too far. The only minor issue is that there is currently construction going on in the building, which can be noisy early in the morning if you had decided to stay out late enjoying all of the vibrant nightlife that Lyon has to offer. However, the construction would not remotely prevent me from returning to this apartment--it was impressively thoughtful and well-laid out, and this thoughtfulness is obviously what has earned Nicholas his SuperHost status on Airbnb. We would definitely return, and recommend.
