My three friends and I had a great stay at Gregoire's place. The apartment was small but very charming, perfectly located and the bedroom window had a beautiful view out over the rooftops of the Marais. The sleeping arrangements consist of a double bed for two, and a mattress on the floor for the third person. As I was the third person I slept on the mattress and can attest that it is very comfortable and I had a good nights sleep each night. I would definitely stay there again.
