This apartment is classically beautiful and well decorated. Some furnishings were high-quality antiques. No AC, but decent cross-ventilation could be obtained by opening the large windows in each room. Beds were comfortable. Closet contained extra towels and other linens. Many electrical outlets. Abundant French literature in each room, including the toilet!
Location is great for those who plan on using public transit. There is a small grocery store literally steps outside the door to the apartment building. A Lidl is around ~1000m away.
The apartment is on the 7th floor. Access is available only via the service stairs and elevator. The service stairs are narrow and circular (angled steps). The stairwell is poorly lit. The service elevator is literally smaller than 2.5' x 2.5' (~75cm x ~75cm). None of this was a problem for us, but I can imagine how others could find it problematic.
Guests are expected to wash all dishes and put them away. We had a misunderstanding because we presumed wrongly that it would be sufficient to just clean them to the point where they were dishwasher-ready. Nothing was specified explicitly about dishwashing, and a cleaning fee was assessed.
Wifi was unusable due to contention on the 2.4ghz spectrum, but Clara hopefully will upgrade to 5ghz soon.
