Jeanne is an amazing host and a very nice person, we felt very welcome in her apartment.
The apartment is walking distance from everything and close to Chatelet which is a major hub. It's in a secure historical building in a colorful but friendly neighbourhood. The apartment is on the top floor, no elevator but the stairs are OK. There are three bedrooms and living room/kitchen (fully equipped) a bathroom and a toilet+shower room.
The apartment is lived in so it is stocked with all the little necessities like umbrellas and plastic wrap and it's clean.

All in all it felt like a stay at a friend's place. Awesome!
