First, the location is among the best I've experienced in many visits to Paris. Quiet street in the heart of the Marais with a wonderfully charmingly wine bar and cafe directly across the street with great staff and a cute dog.The apartment itself had some oddities. Like most Paris buildings there is negligible climate control for hot weather. Leaving the windows open all day was essential despite lack of screens and full length windows opening directly to a shared patio. We felt secure, but this was a necessary leap of faith given the extraordinary heat. The layout was quite strange. Despite the listing, there are only two toilets (one in a tiny separate room) and three showers (two en suite, the other in a traditional bathroom). For such a large space, there was almost no place to hang or store clothing. Finally, the sub basement level is a trip, with some very distinctive features. Although it was somewhat cooler and dark, the underground setting had almost no ventilation (which meant a strong smell of chemicals or mildew). The downstairs mirrored bedroom, also, was a fascinating choice for the brave. Be aware that no door separates it from the cinema room. With some trial and error we did get the projector working to watch the World Cup (which was fun). Check in was smooth, so between that, the quiet setting, and supreme location, I would recommend only with some notable reservations if you can accept the quirks of the place.
