My mom and I stayed at Charline's flat in July. The flat had everything we needed and the sofa bed was even made when we arrived. I had some trouble unlocking the door (user issue rather than an issue with the door) and she replied immediately. The flat is warm but we slept with the window open and it turned out to be quite pleasant. I also like that the flat is near to the Metro station and getting to the major sights was quite easy. The Eiffel tower can be seen from the bottom of the street and is about a 2km walk or a short bus ride. There were plenty of grocery shops in the area and also a pharmacy nearby.
