We stayed at the apartment for one night, we left at the end of the night and came back at 4am. Someone had broken into the apartment, the door was completely open and the lights on. The apartment was not secure enough, there were no anti theft protection, since the apartment door is actually directly on the street and the door was too weak. There were no alarms and we do not know how long the door was open until we got home again. So I advise that the apartment owners increase the security, we only lost money and a passport (it did cause a lot of trouble and money to renew it) but something way worse could’ve happen like arriving while the robbers are still inside.
The staff was helpful and they came some time later to change the locks, it did take until 8am but they postponed the checkout for a couple hours for us.
While the robbery was not the fault of the host there was little monetary reimbursement for what was lost or the fact that we lost a night of sleep due to the robbery and door replacement. The door lock was also replaced with a similar lock.
So, the apartment was really nice and clean, the staff was helpful, but we just want to warn the next guests that the neighborhood was dangerous and the apartment is not secure enough.
