The apartment was fine. We booked it at the last minute because our original booking cancelled on us in short notice. The apartment seemed clean, had soft towels, and provided soap.
But it's not ideal, small things were unexpected and sort of unpleasant. There's a baby on the other side of the wall which woke us up crying in the morning 1/3 nights. The elevator only takes you up to the floor below the one you're staying on. I'm 5'1" and couldn't stand comfortably in the shower, and there's no hook for the shower head except the one by the faucet so you have to hold it the whole time to use it. There's also no shower curtain so you have to be careful. The key stuck in the hole without unlocking the door for us a few times which was really frustrating in the heat of Paris.
It could have been much worse and was a fine stay, but these are things we wish we knew ahead of time. I'd stay again, since the price is probably around the best you'll get in the area.
