I would recommend Cécile's place to anyone I know visiting Paris. This is mainly due to her and Jules amazing hospitality (they are also both insanely cool people). The apartment itself is 10 minutes by walking from Gare du Nord and extremely close to many metro station's that have you in Central Paris very quickly. The apartment itself is spotlessly clean and you are guaranteed to have a great sleep in the bed. My favourite feature of the apartment is the amount of light that streams in. It is a very sunny apartment. Cécile is so warm and kind, and will make you feel very welcome.
