Pauls flat was as displayed on the pictures and the description. The nearby metrostation made it easy to get to the center in about 15-20 minutes. I wouldn't recommend to walk the whole way to the center when you're just staying for a few days. However, the area felt safe and the building was very quiet. Check-in was easy, everything in the apartment worked well. The bathroom had a little bit of mold on the sink and the shower (but it wasn't that bad). A few more towels would've been nice, as there were no extra towels in the spot where they were supposed to be. Further, the bed sheet had a few stains on it, I don't know if they just didn't fade in the washer or if it had not been washed - they did smell clean though.
Over all, it's a very quiet and inexpensive place in Paris but we would prefer a place that's a little bit more clean when staying in Paris for the next time.
