Madame Hélène's place is perfectly located. It is close to the metro, restaurants, the Eiffel and the Seine. It is in a quiet cul-de-sac in the best part of Paris. It is perfect for exploring the city.
Madame Hélène was very kind and helpful. I forgot my passport at her place (and only realised this once I was at the airport) and she drove all the way to the airport so that I won't miss my flight.
The room is nice and quiet and is adequate for a solo traveller.
