I booked a non smoking room, but when i open the door the smoke smell was too strong. The staff give a new room to me, which is better than the first room. But what is surprising me is the door key is the same with the first room. Plus there is no additional lock from inside. I feel unsafe all over the night, anyone can open my door when i sleep. There is also lots of stained on the bed linen. Not sure if i will recommend this hotel to my friends.
