This flat is in an excellent location but otherwise our most terrible experience on Airbnb. It is clearly overpriced, smaller than on pictures and in a very poor condition. It is not very clean, looks shabby, the lighting system is not working properly. We found only 2 switches that actually turned on lights and bedroom had only a small table lamp as light source. But the main problem was the awful smell, a mix of sewage plumbing, chemicals and maybe cigarettes or mold. It was everywhere in the flat, even on bed linen and got into our clothes too. We could not sleep because of it and woke up with severe headaches. The host did not see the problems and said that all this is perfectly normal in Paris.
We stayed for 1 night out of 5 we booked. The host changed the code of key box after we left but refused to refund the nights we could not stay. Agreed to refund only 1 night although we could not even get into the apartment we had booked.
Luckily we got a full refund after reporting the travel issues to Airbnb.
