We (a family of 4) arrived to the house to stay for one month. The location was good for us because it was in close proximity to friends and relatives.
Opening the front-door we were met with a sour smell. Inside the house we slowly discovered a serious mold infestation. Contacting Airbnb for help was extremely slow and unhelpful. Since it was in the middle of summer holiday it was not possible for us to find an alternative accommodation by ourselves, and neither the host or Airbnb attempted to help us. Since we traveled with kids who began to struggle with coughing due to the bad air inside, we decided to clean the house ourselves. After 9 days living in the mold infestation the host arranged to have the ACs cleaned. Although both helped, the house still needs a lot of work.
After 15 days we managed to find another place to live and finally got to move out.
It is sad to say that this ruined more than half of our trip, despite costing an arm and a leg.
