Yayuan Tanglang Hotel (Shenzhen Xili, Southern University of Science and Technology)

The hotel is dirty, damp and smells. You can hear everything happening in adjacent rooms. I got a room without windows (I didn't know that this is even possible). It is called "boutique room", hahahaha. The floor in my room is bulging, and if I use water in my toilet sink, after some time that water comes from under the floor on both sides of my bed. I complained but there were nothing the hotel people could help me with: there were no other rooms available, they offered a small partial refund if I cancel, but too little and it was already too late at night. The breakfast is very basic and tasteless (without even coffee), but it's much better than the room. If you fancy particularly ugly hotels, give this one a try.
