My sister and I shared a twin room. Room was clean but we got no sleep as people were shouting and partying all night. Eventually I had to go and complain at 3am. Staff did speak to the room that was making all the noise but a hostel this size should be checked regularly to make sure people are not getting disturbed. No evidence of this as noise went on for hours before I got up to go down three floors to complain.
