It's a beautiful historic apartment in a nice building. We visited with 2 small children (1.5 and 2.5 years old). There were amenities for the small children. But it is also a very kept and we definitely had to pay attention to make sure our kids didn't get into trouble. It's a beautiful part of Paris, but also nice to get away from the tourist crowds. Convienent to the metro right out the front door. Restaurants and a grocery store are very close by. All of the check in and logistical details were fantastically executed and response from the owner was very quick.
A few notes...the master bedroom, dining room and parlor are all street facing so it is noisy with the windows open. The door to the building is on a busy street so was challenging to unload/load rental car & uber.
All and all highly recommended.
