Bérénice is the best! She welcomed me when I arrived and we had some really nice time talking and sharing. The apartment is nice and cozy, sparkling clean, with everything you need for a good experience. She also give me very good advice about museums and how long I shall need to visit each one. Also I got this ballet ticket from a website of her recommendation for almost half price to a lovely show. Four days is too short, I will definitely visit again if I come back to Paris. This apartment is literally at the heart of Paris. Convenient to walk to almost any famous spots.
