I've noticed others have said it was cold during the night, but after staying in the 'Joy' room I can say that it was just that, a joy! There was a small heater and the duvet kept me nice and warm throughout the night! My best sleep for months!
It was also extremely safe, locks on all doors and even a gate outside which meant I was comfortable leaving my items behind and knowing they were safe whilst I traveled around London.
Check in and out times were comfortable and meant I could get in a little later than planned.
If I was staying again, I'd make sure to book on a day where I could go to one of the morning practices or learn a bit more about there as it is a really interesting stay!
