 The smell that seemed like it was cannabis which after the cleaner came and sprayed a small amount of spray to try and hide the smell did not leave When asked they explained this was through the air vents but was unbearable in the morning Also when we went into our room there was already someone else s luggage there but after ringing reception we were moved rooms The smell though was unbearable 
 How close it was to the o2 and that there was an entrance from the hotel to the o2 Bed was really comfy and great shower and bath
