NIHAO Hotel Chengdu Vientiane City

I booked the hotel for 9/18-9/22, I arrived on the 18th, but the woman in the front desk forced me to pay for the 17th as well and there's a man who was sleeping in the lobby of the hotel told me the same thing. I told them that it's already 9/18, so it's not fair for me to pay for the 17th, they don't care and refused to allow me to stay in the hotel! I had to leave 1 am in the morning and it was dark outside and there was no people or traffic outside.What was worse is that the hotel stairs outside is very steep and slippery and I fell on the stairs, I broke my glasses and injured my face and right eye, but the man who seemed to be the manager didn't even pay any attention or saying anything as a human being, such as " are you okay?", I was in so much pain and I carried my 3 luggages in the dark outside walking aimlessly didn't know where else to go, because I was not familiar with Chengdu! Fortunately I stopped a taxi driver and he drove me around and I found a hotel later on. I was in pain for a few days and my right eye 2 days later with bruises like a raccoon eyes! It's a horrible horrible experience and the hotel staff didn't even behave like humans! Avoid this place by all means!
