We stayed in a 3-bedroom apartment. There was a problem, one of the rooms was locked from the inside (the door lock is old style, the lock part was accidentally pressed when the door hit the wall). Called the reception (twice), they said they would send a technician to the unit. Up to 2 hours, no officer came. The room service officer came to deliver an extra bed, but also did not have a spare key to the room. The officer called the reception again, but still no technician came. The family took the initiative to try to open the door by all means, finally it opened. Until check-out time, no officer came or the hotel followed up on our problem ☹️
