We were a family of 4 and we found Juliette's apartement perfect for our 6 days stay in Paris.
The kids (11 and 5) slept on the folding sofa in the living room and we had a great bed for my wife and I. The apartment was clean, it was exactly what is described on shown on the pics.
The neighborhood -Montparnasse- is great: services like supermarkets, pharmacies, bars, restaurants are there. The metro is 5 minutes away from the flat. We cannot complain about anything.
Communication with Juliette was fluid, quick, effective. The access to the flat easy... We had a great experience. FIVE STARS!
