I can highly recommend Bertrands apartement. Everything was very clean and personal, perfecetly located in a very lively part of Paris. The stairs to the apartement are a nice little everyday workout, which enables you to enjoy the french cuisine without regrets ;)
Communicating with Bertrand is super convenient and he even made a very late check-in possible, thanks to his friend Cecile. The Metro station is jst around the corner but exploring the city walking is also possible.
