The apartment was clean when we arrived, but we had to wait outside for 30+ min for the greeter to check us in. Three of us stayed comfortably in the apartment with one twin bed in the dining room, one full sofa bed in the living room, and one full size bed in the bedroom (with a door). I think it could accommodate 4 people comfortably, but 5 is pushing it.
The shower fluctuates a bit in temperature, but nothing drastic and still totally usable with good water pressure. The dishwasher was great as well as the washer for clothes. There is a drying rack in the bathroom. We had issues with the WiFi disconnecting periodically. Resetting the router helped a bit, but we still encountered disconnections. Luckily, we were not spending much time in the apartment during the day.
The location cannot be beat. It is close to three different metro stops which makes it incredibly convenient to travel the different lines to different areas of Paris. I would recommend going to BO&MI bakery which was 3 blocks away.
Aside from the check-in issues, Antoine was very prompt in responding to messages. I would recommend staying here.
