My friend and I stayed at Sylvain's apartment for four nights. He was very helpful before as well as during our stay, and made us feel so welcome even though we never met in person. The apartment is really nice, and corresponds well to the pictures. The view of Parisian rooftops and the Eiffel tower from the balcony is so magical, you have to pull yourself up to make it out to dinner at night. It's highly recommendable to take a glass there during sunset. The area is great too. All in all, a wonderful experience!
