Clean, Cozy, Conveinient. We stayed 4 nights and enjoyed it very much. Liked extra clean floor, bedding and towels. Blackout curtains were useful when taking a nap during the day. Also there was a hair dryer which was missing in the amenity list. Laurent's flats are definitely the first choice if we visit Paris again.
But as seen on the photo there are narrow stairs and no elevators. If you are travelling with large heavy suitcases, it could be quite tough to carry them up or down.
