I would not recommend staying here. The area felt very dodgy (I have been to Paris 5 or 6 times previously so am generally pretty comfortable and know what to expect). The building was in a pretty poor state.
Charles was away at the time of my stay. He had a friend meet us. She initially didn't answer texts or phone calls. This was resolved with a call to Charles.
The photos on Airbnb are not representative. The apartment looks like it has seen better days. The bathroom cabinet door was rotting. The paint was not in great condition but not a deal breaker.
When we arrived the bed was made up but the couches not (I had discussed this with Charles previously, he was aware we were a party of 3 but needed 3 beds). The sofabed was broken and unable to be opened properly. The mattress for the sofabed was pretty dirty.
On making up the beds it was clear the sheets weren't clean and were covered in stains. One stain was very gluey and I don't want to think what it may have been. I left and didn't stay here, my family and I ended up booking a hotel. I would thoroughly recommend reconsidering booking this place.
