We didn't meet Harold in person. To enter his house there is a codes system which allows you to get in without meeting him. Everything is automatic and it seems like to enter in Fort Knox! :-)
The house is, to me, in one of the most beautiful areas of Paris, in the art district, close to the Seine, Louvre, and Odeon with its bars and little shops, moreover, the house is old style as structure but very very modern and fully furnished. We had a wonderful time there!
