We have a good time in Paris, in Sylvio's apartment. It was comfortable (big sofa and balcony for small cup of coffee in the morning), clean and quite neighborhood as well for us, close to metro and Franprix, and he provide us with parking spot :) nice, since parking is so expensive in Paris.
Sylvio give us quick response (thanks for giving us an estimate time with metro to Eiffel, and maps), welcome us with kindness and smile (big thanks for it). I wonder 4 days in Paris is not enough :D
Big thanks for Sylvio :)
