A terrible night with little sleep. Shame that the room had no heating/air con control. We were unable to reduce the temperature below 24 degrees. At 4 am, after a few hours of intermittently messing with the control box & no sleep I called reception. Maintenance did arrive in Within in 45 mins. They said the valve had stuck & set it to the required 17 for us. But alas it never achieved below 22 degrees. I registered a complaint yesterday morning when checking out, but get the impression I won't hear back!
Otherwise a lovely room (tower 1714). Great location. Good breakfast.
