Usually a great stay but i was woken up and accused of being in the wrong bed in the middle of the night by security. I was very obviously in the correct bed, and a simple look up in their system would have verified that. A guest who was not even registered to be in that room was in the room and accused me of being the wrong bed, asking about missing items. I very quickly showed my check in materials to security and asked why another unregistered guest was in my room and why they woke me up without looking any of this up. No answer. I went back to bed and had a rough morning. This is extremely bad security protocol. I recognize that shared rooms will have some inconvenience but this bad security protocol (wake up registered guest and allow unrelated unregistered guest into registered guest room) makes me question the safety of the hostel.
