My experience with Lucky D's hostel was far from being acceptable and actually very surreal. At check-in, I was given a bed belonging to another guest (that was out at that time), meaning that when he came back at 2am he found his bed occupied by me.
I had to pick up all my stuff in the middle of the night and go to another room, just to be waken up AGAIN just 30 minutes later by another guy (he had just come back from a night out with his friends) because apparently I had been assigned his bed. Meaning, I had to get up again, pick up my stuff and go to the reception, hoping they would assign me a bed not taken by someone else.
Just to find out that all beds were taken and the system on their PC was "messed up", obviously due to a human error I would add. Thankfully, while waiting at the reception at 4 in the morning, a guy came to check out, so I was assigned his bed and could sleep without being told to move bed again.
Just for completeness, while waiting at the reception, another guest of the hostel came to complain that her bed had been taken by a random guy, so my issue was not just a coincidence but actually happened to other people too.
