It is the first time that we have such a bad experience with Airbnb. The owner did not want to provide a second blanket, two window doors could not be closed, one could not be opened, chairs on the balcony were not usable since they did only consist of large rosty grids and there were no pillows for them.
Despite not being able to close the doors, Airbnb did not reimburse accordingly when we had to leave earlier due to missing security.
