I arrived for check-in at 2am and proceeded to my room which was a walking distance from reception only to find the room open. When to my colleague's room to call reception and all they did was tell me to just go in because there is no one in the room.
I had to beg my colleague to go with to inspect the room and indeed there was no one but the door frame was tampered with hence when the door is closed softly it opens after a while.
i called reception to report this but again no alternative room was offered. I will never go back there.
