Great location in the heart of Paris. This open space duplex is located on ground floor facing the inner courtyard of the building, very secure and calm. Nicely decorated and well provided, included multi channel TV, wifi and fans (but no a/c). You can technically accommodate 6 people but I would recommend 4 as the upper section of the duplex where 2 extra beds are located have extra low ceiling and not good people who are a bit claustrophobic like myself.
for people driving in: no free street parking in Paris intra muros and extremely expensive and time limited ( 50 euro for 6 hours but free overnight from 19:00 to 9:00), note that if you drive 200 meters north you are in a cheaper zone (see details on the Mairie de Paris website) I found a relatively good deal in a Parking of the Defense 4 Temps commercial center through the OPnGo app. (seamless and you can reserve just a hour in advance) for 20 Euro for 24 hours. Hope this will help.
