Terrible communication, we had to catch a flight in the early morning. We closed the door off our air bnb and went downstairs with our lugage. The main door to the appartement building was stuck apparently you needed the key from the airbnb but this was in the appartement itself where we were locked out of. There was no way to contact the host at this hour and there was no emergency exit nothing! We had to wake up one of the neighbours at 4:30 so this took about an hour and due to this we almost mist our flight! If i can give one recommendation for the host is to put an emergency key for the door in a secret location in case of emergencies like this. Worst and most stressful experience i’ve ever had to deal with on airbnb.
