It’s the perfect apartment for a few days of visiting all the famous sites of Paris. It has no air conditioning, but it’s not needed most of the year, and each floor has a good fan. We are used to having AC all the time, living in Florida. We also came with children, and we did fine. Our children are already teenagers though. I do not recommend it with young children. It can be loud at night. It’s a small place. It’s on a 4th story with no elevators and the stairs inside the apartment are narrow. It’s a great bargain though for it’s perfect location. You are surrounded by metro stops, including to several RER trains, close to Gare de Lyon, and with a large shopping mall two blocks away.
