Hèléne's apartment was the perfect place for two of us to stay. It's a good size and located within a few minutes walk of several metro stations. We didn't meet Hèléne but her sister met us in order to let us in, and she was friendly and informative. The wifi was fast which was good for us to help navigate our way around! Was helpful having to not check out in the morning too as it meant we could leave our bags while we had a few last hours of exploring :) Would definitely recommend, and would stay again if returning to Paris!
