The house was robbed while we were out on the first day of the trip, and both airbnb and the host did not do anything to make up for it. We lost more than 700 euros in cash, two laptops and a jewelry of 300 euros. If this is not an enough reason to stop you from choosing this house, I will list a few more more details.
According to Barcelona rental regulation, the host is supposed to provide an official complaint letter and should be able to have an emergency contact 24/7. These were not the case either. They did not answer the phone several times, and occasionally ignored messages. There was no instruction on fire extinguisher or first aid box, which is also against the regulation.
When we found insects in the house, we reported it to the host and he said that they have sent in a cleaning team. It was the day when the house was robbed, and they rejected to provide us the contact of the cleaning team, only saying they've been working for the house for several years and that they cannot be blamed. After all the insects were still there, so I am not sure what the cleaning team did.
It is taking more than a week for the host to merely file the case to their insurance, and they have ignored the request to provide an evidence that they are going through the process. They said that since the lock is not broken, it is not very likely that the insurance will cover the case. We have documented everything the police instructed us to do, but the host said that the it is not enough to fulfill the insurance requirements.
