Definitely the best location to explore Paris! Everything you need is in walking-distance, Louvre is just a 10-15 min. walk away from the appartement and there are plenty of very good restaurants around the corner.
We checked-in at 14:00 and had to wait a few minutes together with Alex until the appartemend was cleaned. Sometimes it‘s very loud when neighbours walking the staircase, but during the night it was quiet and we slept very well. I can definitely recommend this place!
