We stayed for 5 nights and were satisfied.
The host gave us advices quickly soon after I asked "is there a supermarket near here?" for example.
Great location. Only one or two minutes to the metro station, that connects directly to Concorde, Opera and Bastille. You can also walk to the Eiffel Tower and
Champs-Élysées street by 15 or 20 miniatures.
The room is not so big. Around 20m2. Good for 1 or 2. The only thing you should now in advance is there is no elevator to 6th floor. But as long as you can endure it, the room is great for touring Paris.
