Charles made us feel welcome at his place and was very helpful despite our Eurostar delayed 2 hours.
The flat is great and the location on rue des maryrs is perfect: there a lot of restaurants, delicious "boulangeries", "patisseries" and "fromageries".
A special mention for the boulangerie/patisserie just next door, the brioche and croissant we had there were simply D E L I C I O U S.. ;-)
