It was our worst Airbnb experience ever and ruined an important part of our summer holidays. Although we have made a 5-night reservation in this room we only managed to spend one night there. There was an intense musty smell in the room which made our stay unbearable. The cupboard next to the shower was full of humidity and mold, caused probably by defective renovation works, which contaminated the ambient air of the bedroom. Besides, odors of dust and bacteria seemed to come from the air condition whose filters were obviously never cleaned. During the night we spent there, to avoid a respiratory problem, we opened all windows and doors but it was so noisy that we did not manage to sleep at all. As the host was reluctant to give a satisfactory refund I spoke with the Airbnb Support, I sent them photos of the condition of the room and got a partial refund of the amount paid. This room violates national regulations for renting and Airbnb Hosting standards as well. I hope that no one else will have the same experience as us.
