Lovely apartment. I stayed at Alessandra's apartment for 5 months. It is quite big, even enough place to stay there with 4 people due to the cozy sleeping bed. Nice style, well equipped, clean apartment and in super good conditions. New Windows, so no noise from the street, new heating system and well working Wifi.
Check in and check out was well prepared.
The area is super nice as well. Directly at the Champ de Mars and the street is full with nice grocery stores. And many nice places like Champs Elysee, Invalide etc. is within walking distance.
