To avoid. We had stayed for 3 weeks in July, in a supposedly quiet place. However, every 6:30 am, we are awakened by the noise of children upstairs shouting and making loud footsteps. We had discussed several times with the family above, explained to the owner of the AirBNB to ask to make less noise but nothing is done. The owners explained to us that they would go and talk to the family above, which the family explained to us after discussion that the owners had not done so. I needed to sleep for work, but apparently nobody understands. Another day, the smoke detector or carbon monoxide alarm rang and only my companion was left because I was at work. She left the apartment quickly thinking there was a fire in the building but without the keys. But in fact, the alarm had rung because of the lack of battery: they did not check the conformity of the apartment security.
They wanted to make us pay the fact of reopening the door (because they do not give us the double of the keys, they keep it for them) by pretext that the person who had the double of the keys went out of work to open us (whereas I went out of work to regulate this problem) and say to us then that we "had chance" he was not at work therefore it was necessary to pay 20 euros to open a door. We paid 20 euros because they do not check their safety thus by their fault. I wanted a proof of invoice to justify my departure to work but they were at the beginning retissent to make this invoice. They finally made it to us but not mentioning the premeditated departure of the apartment by the companion. They just specified to open the door but not because the alarm rang because of a lack of battery (especially since it was me who changed it).
We pay an AirBNB a little expensive for calm, but that did not hold its engagement, in addition to trying to make it to us in reverse with the history of the keys. I see some comments explaining the dishonesty of the owners, which is not shocking to me.
