From the little touches for a busy traveler (lots of plugs, USB ports, hooks) to the beautiful decorations and superb and quiet location, this was a great option for our group of four adults and one toddler. We took the biggest bedroom which fit the pack and play crib and it was really helpful having a tv in the room when our little one (and us) were up super early and jet lagged to watch Netflix without disturbing the rest of our party.
Some tips we found if your party will include a toddler, the Elie Wiesel park about 2 blocks north is great for the playground and for watching ducks and herons in the pond. The Musée de la Chasse et de la Nature and the Picasso Museum are both very close but unfortunately, we weren't able to check out the first one because it was under renovation and the latter closed because of the national strikes. The marche des rouge enfants nearby was a good option to grab a quick lunch (with different options for everyone).
The only minuses were that there was 1 towel provided per guest, no floor mat or hand towels, and the internet was very spotty our entire time. I reset the router several times per the instructions but it was never strong enough to work from (which one person in our group needed to do for a few hours one day).
