Terrible experience. My partner and I were celebrating and we had previously stayed at the Radisson Red in Glasgow (which is very good). We checked in and were shown our room, only to discover the beds and pillows are different. The bed was firm, and on going to bed we discovered that our room was directly under water looked to be an air conditioning unit; it sounded like a jet engine cycling. My partner had important meetings, and reception told us the only thing they could do was more us to ask upgraded room at nearly midnight. We repacked and were taken to a smaller room with an equally uncomfortable bed. I spoke to the manager the following morning, as we had another room booked a few nights later due to the way we travel, and was reassured they would "take care of us." On return, we did receive an upgraded room with a larger bed (not really more comfortable) and found vouchers for drinks and breakfast. Fair enough. The breakfast was okay, but after a day in Liverpool we returned to retrieve our bags and claim our cocktails -- only to be rudely informed at the bar that our vouchers included only wine, beer, and soft drinks. Except the voucher said no such thing. A tall woman with glasses who seemed to be managing the bar became extremely abrupt, and it was only after going to reception again that we were able to claim a couple of cocktails. When the time came to leave for our train it was a relief.
Darren, Tom, and David were kind. But just avoid.
