Pierre (we didn't meet Clémence) was very friendly and welcoming and we felt like we could make ourselves at home in the apartment. The apartment is in a great location, very easy to get to from Denfert Rochereau (with easy confections to anywhere in Paris), and a short walk from lots of great shops and restaurants around Rue Daguerre. The room is spacious, with a large balcony, and the bed is very comfortable (doesn't feel at all like a sofa bed). All in all a great find in a great area, highly recommended.
