The apartment is well located, clean, and cute. We stayed there during a heatwave, so even with the window air conditioning unit downstairs and the Dyson standing unit upstairs, it was still very warm in the loft (where the bed is). I imagine this is not as much of a problem during normal temperatures (or seasons other than summer). This apartment (and the neighborhood of Montmartre) is not well suited for people who have trouble climbing stairs/hills.
