We truly loved staying at this beautiful flat. Delphine was an excellent host with great communication before we even arrived. She sent a guide where we could learn more about the area (shops, cafes, etc..) The flat is on the 6th floor, but there is an elevator (lift). There are only 2 toilets, but we didn't find this to be a problem, even with 8 people. There is no central AC, but you do get a nice breeze when the windows are open. There were only like 2 days where we were hot and wanted a fan (but we are Southerners from the U.S. and love some AC)! I would recommend this flat to anyone wanting a true Parisian experience.
