I went wrong room cause there was very dark. And couldn't see properly. I requested to host change the right room but he said "You got into the wrong room, but the other guest has now got into your room, so please stay where you are. Thanks. " I said okay. In the morning, I realised the guy changed the number of lock to into the room. So was confined for few hours. I called to host many times but he didn't answer at all. I called lock Smith then charged me $240.
