Very nice apartment over the roofs in the 9th Arrondissement, cosy for 2 persons. Communication was friendly and immediate round the clock. Check in at midnight by key box was very helpful. Check out happened personally and completely uncomplicated, we were very grateful to have our luggage there up to our departure. Bed and bathroom very clean. Just a slight restriction: The kitchen is narrow, one person can just stand there, pans were a bit used.
We were absolutely happy with our stay and recommend the apartment to everybody - liking sports to 6th floor.
