Pros: Great location near metro, shops, restaurants, walking distance to lots of major spots (Louvre, Jardin du Luxembourgs, Notre Dame). Clean, modern apartment, amazingly quiet with windows closed.

Cons: Super hot in warm weather, and noisy with windows open---right above a bus route. Rather barebones/scrappy in terms of accoutrements of daily life. (Think flipping your egg with a wooden spoon and chopping your fresh veggies from the marché with a cheap steak knife.) Lots of burned-out lightbulbs. Barely enough dishes/silverware for four people. No paper products/dishsoap/laundry detergent provided. Drying rack broken. Definitely furnished with leftovers from an overseas move and administered from afar rather than a place that someone is truly meant to live in.

This isn't to say it was terrible--just a bit overpriced with respect to creature comforts given the cost. For adults who will spend little of their visit in the apartment and prepare few meals, these things will likely not much matter; families may find it a little less pleasant.

Windows open to the floor, so that's another hot weather minus if you are traveling with very small children. Stairs to (Am.) 3rd floor weren't super onerous for our almost 3 y.o. however.

Not a bad place for winter/spring/fall, but I would definitely think twice about booking here or anywhere on 2nd floor or above in July or August without A/C. Parisian solution to the heat is to leave town, and I suspect most apartments reflect that. We actually ended up spending an additional 80 euros on fans at Monoprix to make the place sleep-able during a heatwave. (So future guests should at least have that as a fallback!)
