A GEM. The location is perfect, right at the hearth of the Marais, close to everything, including the metro. The apartment is beautiful, nicely furnished, well above AirBnB standards (at least in my experience). The place is also very sunny (double exposure on the top floor) with a nice view of Parisian roofs, and very quiet since it's in an inner courtyard. Internet is fast and reliable. Ivo was extremely friendly and always available. Overall, very highly recommended!
