My room was freezing cold. Outside would have been warmer, which is saying something for London in January.
After leaving my bag there following my initial check-in, I returned late at night and it was so cold that if I had slept there I would surely have gotten sick.
I was unable to raise the temperature and, after too long a wait (which was somewhat understandable given the late hour), maintenance was unable to fix it and I had to change room.
And, of course, I was woken at 8:45am by housekeeping banging on the door because I hadn't left the Privacy sign outside the new room.
All of my interactions with staff were friendly and I have no issues with any individual but no-one should ever have been put in that room.
