Ah Ah I can provide information and pictures about what I experienced with this flat and this person.
I use to travel eveywhere in the world and have already rent 3 flats trough Airbnb.
This one is the worse experience we (my wife and I ) encountered.
This person has to understand that he has to provide a service (ie: a real bed, clean sheets...) for such a price.
As he is not the owner of the flat he may consider that it's just an easy way to pay his own rental....
