It was my first time in a hostel, and the experience wasn't the worst but there were some things that didn't go so well.
I arrived one day at night and was told that the check in finished at 1am, and at 00:30 I sent a message saying that I would arrive later than that because I had a problem with the airport shuttles and nobody answered. When I got there I called several times to the available numbers, including an emergency number that is provided and no one answered! My luck was that I managed to sleep at a friend's house because otherwise I would sleep on the street. I understand that the check in time is until 1 am but in an emergency situation no one is there to help. I was told the next day that the phone was on silent and they apologized but did not return the money for the first night.
So I was a little disappointed. Because I didn't think it was fair.
Apart from that everyone was very nice.
