We didn't get the chance to meet Antoine, however we interchanged a few questions and he always responded us super fast and accurate.
Also, his friend helped us a lot by carrying our luggage the 4 stairs floors. In addition, gave us a map with everything we may need for our staying (chocolate houses, food stores, etc.) and offered his help if needed.
The place was exactly like the pictures, very cozy and clean, great bed although we were a couple and were 2 separate beds, but still awesome and comfortable.
Highly recommended if you want stay in the center of everything!
