Nice little 6th floor studio with elevator access next to Galeries Lafayette. Location is near multiple metro lines (7, 9, 3, 8, 12) where you can reach anywhere in the city. Plenty of restaurants of all kinds nearby (recommend Berliner Das Original Kebab and Qiao Jiang Nan in particular), as well as a curated selection of France's greatest pastry and chocolate hits at Galeries Gourmet (Pierre Herme, Jean-Paul Hevin, Alain Ducasse, etc).
Fridge, washer/dryer (single combo unit), shower and toilet worked fine. Windows can be fully opened for ventilation (standing fan was missing a power button when we visited, but the city was relatively cool in springtime so we didn't need it). Kitchen sink drains slowly and the front door handle is loose and can only be opened using the key, but otherwise the unit is in decent shape, and highly recommended to use as a home base if you're traveling by yourself or with one other person, choosing to eat most meals out.
