 Not sure if it s because of the room location about every 30 50 seconds you can hear the underground metro passing by Have been allocated the room right in front of the security door each level has that once ppl access the door to take the lift or enter the room area you can hear the door bang every time Hardly sleep at all till all the ppl go to sleep and no underground 
 The room provides different cables to connect your device Very considerable Good location very short walking distance to underground and the riverbank as well as a supermarket and nice restraurant
