Good communication, flat as on pictures, v close to Palais de Congres, indirect light - including in bathroom - thus make-up can be a challenge if you need to shine in a congress, mattress was nice and tight and just about ok for my size (176cm); as indicated its a smoker apartment and you can feel it; overall we recommend the place if you want to walk to the congress centre, quick access to metro to Paris center, full equipped kitchen and feeling of living in a true flat.
