We stayed for a couple days in this apartment. The location is really great. You are in between two metro lines, which makes you easily visit all nice places in Paris within a maximum of one transfer by metro. Furthermore the area around the apartment is really warm with a nice centre, restaurants and bars, but not many tourist, it felt more a local France area. Hence, you don't hear any noise from the street at the apartment. The apartment is indeed on the fourth floor without elevator, but wasn't any problem for us. The shower is a bit low, but the rest of the house is nice and the kitchen is also fully equipped. We definitely would recommend this place (also the contact with Jonathan was really quick and easy)!
