The flat is great located. The quarter is perfect, quiet and full of pretty "Ateliers" and "Salon de Té" and 10 min far away from the Louvre.
The apartment is quiet nice, enough for 3 or 4 persons BUT it was REALLY DIRTY. It seems to have been never cleaned or almost since a very long time. There is also a strange and perturbing noise in the bedroom when you or someone in the building use the cold and/or warm water.
