The apartment is large and lovely! We had 5 people and everyone was completely comfortable. Everything was clean and ready for us on arrival. Two bathrooms was also plenty and worked easily.
Michaël, the Butler, was wonderful responding quickly and solving any issue we had, of which there were few. It is great to have him as a resource.
Location is fantastic, close to so many top sites and several Metro stations.
Only key thing to be aware of is the noise from the small park and the music place next door which has events on some nights and the people noise gets through the historic floors and window doors. If you are not used to big city noise, bring ear plugs to help.
We would not hesitate to stay here again.
