Upon arriving at the room (702), the surprised-looking cleaner was finishing up, and left the room promptly, after spraying a few squirts of some cleaning chemical into the air. 
A long list of problems ensued: 
Wifi not working
Disgustingly dirty room
Cold shower
Noise Problem 1 - the neighbouring guests entering or leaving the room close to my room. 
Noise Problem 2 - the Ice machine within 8 feet of my door sounded like an industrial drill upon use. 
Noise Problem 3 - the room that I was allocated, had windows facing on to the outside pavement. On the pavement were the hotel waste bins, about 5 of them, including empty bottles.  These bins were emptied at 2.54am.  
Noise Problem 4 - the noise of the traffic. I could hear every truck passing.  
Noise Problem 5 - the people, especially the woman, in the adjacent to mine, were having sex very loudly. 
Air Conditioning not working properly
Room Aesthetics - loose cables, poorly fitted blinds. 
The Smell - in the room and throughout the whole hotel there was a pungent chemical smell, not at all nice, in fact quite putrid. 
Basement Area - cleaning trollies in foyer
Customer Service non-existent
I have taken videos and photos of the above items. 
I will be sharing the above list of issues and images with Hotels.com as a review and as a formal complaint. 
I have stayed in hundreds of hotels for business and personal purposes and have never faced such disgusting conditions.
