We stayed at Aline's apartment 5 nights, for my daughter's Bat Mitzva trip. We took the bedroom and she slept on the folding sofa in the small living room, which was perfect! There are curtains for privacy and prevention of light in the morning, and it exactly fit our needs.
Everything was clean, all the amenities were available and working well.
But the best thing about the apartment is definitely the location! Close to Les Halle Metro/train station, La Parisien boulangerie and in the center of everything - it was so easy to commute to wherever we wanted to go.
There was an issue with some noise coming from the apartment above at some points, but it might have been coincidental and in any case negligent compared to the other upsides of the apartment.
Aline was responsive and helpful with restaurant suggestions, and overall we had a great experience.
