Penelope was very helpful and responsive to our questions and made sure that a neighbour could receive us at just the time we were arriving. We received great directions on how to get there (we arrived at Gare Lyon) and the location was quite secure with access to through the private courtyard. We love the location with easy access to trains, metro, and even Velib! The place is cosy with steep stairs. It was quiet at night, other than the occasional siren going to the nearby hospital.
