We stayed at the hotel for one night. Around 05:45 AM, we woke up to someone trying to open our door and actually succeeding. However, the security lock we had put on the door for the night prevented it from being fully opened. When I went to the door of our room, I found an unknown man trying to enter. So only the security lock we had put on for the night prevented this unknown man from completely entering our room. As we were checking out of the hotel, we told the hotel staff about our experience and asked how this could be possible. However, the hotel staff just said that what we described couldn't happen and implied that what we told them wasn't true.
After checking out, we left our bags at the hotel reception to pick them up later. When we went to retrieve our bags, the hotel staff told us that they had checked the surveillance cameras regarding our claim and it turned out that an intoxicated man who had fallen asleep in the hotel corridor had given the hotel staff the wrong room number as his own. The hotel staff had opened our room door for this man without ensuring it was actually his room. This entire incident left us with a very unpleasant feeling about our stay. In our opinion, the hotel staff's initial indifferent attitude towards us and the safety of the hotel guests was inappropriate. We did not receive any compensation for this incomprehensible mistake by the hotel.
