On the positive side:
-Great location next to Arc de Triomphe
-Beautifully decorated
-Spacious bedrooms
-We could leave our luggage at their central office after check out.
On the “can be improved” side:
-Late check in (at 16.00) and early check out (at 11.00) with no flexibility
-Only 1 bathroom for 4 bedrooms
-Wifi was not working
-A few lamps neither
-Some noise at night from people quarreling
-No local recommendations could be provided ahead of time so we could better organize our trip in a city as busy as Paris.
