It's a nice apartment. The ad is 100% real. Nice beds, two bedrooms and a guest room that can be used as a bedroom too. Close to subway station, supermarkets and some nice restaurants. It's certainly a nice place to stay and enjoy Paris.
There are some not nice things that need to be added. First, the building is kind of ugly... when opening the door from the street, the first impression is not a nice one, not at all! The lack of elevator and air conditioning can be kind of annoying in a long stay, or during hot weather.
