Christophe is very responsive and the check in/out process was effortless. For those that may not be able to handle stairs, the apartment is on the third floor with no access to elevators. The location of the apartment is one of the best, within a short walking distance to many shops, bars, restaurants, and the metro. It is also within about a 25 min walk to the Louvre, and other major attractions.
Although the apartment is spacious, comfortable, and otherwise clean, one issue that needs to be addressed is the black mold which is taking over the upper side wall and ceiling of the bathroom. This causes the bathroom to smell of mold (a musty damp smell), and if the windows are kept closed the smell fills the rest of the apartment. We kept the windows open at all times and was only minorly inconvenienced but may not have been comfortable if our stay had been longer.
Overall the value and location of the apartment can't be beat.
