It happened on the third morning in the apartment, and we were still in bed. We heard a continuous sound of opening a door with a key, I thought of a thief or a robber and I woke my boyfriend up letting him know that someone is trying to open our door. I was so scared that I could not breath. Our door was opened, we didn’t dare to make a sound. There was only the sound of the man who was mumbling and with footsteps. We were so freaked out and I thought that I would have been killed. Then the guy who came in our apartment turned all the lights on except our bedroom. After the man walking around for like 2 minutes, he opened the door of the bedroom and found us, and we were looking at each other, then we were told that he booked and paid on Airbnb, and we said to him so did we. Then he was like realised that he got a wrong key which we found out that the key was given by the cleaning staff, and he apologised and left, but we never find the key afterwards. So we contacted the owner immediately and the customer service manager came and he arranged a locksmith and asked him to change the lock of the apartment. We appreciate what cs manager did for us，but what happened in that morning was so scary and disturbing that we prepared a knife under the bed before getting in bed and couldn’t sleep well afterwards. Please please please don’t give guests the wrong keys.
