I am Italian but I will write in English so that more people can understand.
I second all good impressions and comments from other guests; Fabrice is a charming man, prompt to reply and very discreet during our stay, and the apartment is truly the Aristocats' come true, with a stunning view over la Ville Lumière and very silent at night despite being located on a very busy Avenue. The position is also greatly convenient, with two Métro lines at a 2-minute walk, taxis and city buses even closer, a large mall and all sorts of supermarkets, shops and restaurants (Frenchðnic) within comfortable walking distance. The apartment is certainly tiny but also quite smart, and for 4 nights we had no trouble staying there even if there were 4 of us (3 adults and one child). However, the view is so romantic that I must recommend a stay to couples in love, for an unforgettable Parisian experience! Merci Fabrice, very best to you and your family.
