Laurence’s apartment is classically French, in a building from the 18th century. The location couldn’t be better. It’s on the fourth floor (what Americans would call a “fifth floor walk-up”). It has no a/c, which made life in a heatwave challenging, but Laurence kindly provided a fan which helped a great deal. There are windows on the front and back of the apartment which allows a cross-breeze, which is also helpful. Another commenter mentioned cigarette smoke; I believe other tenants in the building may smoke, or, perhaps, it was smoke from the patrons at the bistro downstairs; we did not perceive smoking in the apartment itself, just perhaps from other locations coming in through the window.
All in all this is a great place for a couple or a couple + a child in a wonderful convenient location.
