They said Amex was accepted. My card worked perfectly fine, yet the machine refused it.
The room temperature was very bad and could not be adjusted during the night. I was freezing!
The next morning when I mentioned it to the receptionist, he did not action anything.

I hate these "hotels" more every time I have to stay in one. They are not hotels, they are soulless, characterless people storage units. The foyer is designed around a 24hr ATM lobby, the rooms are too cold and the bathroom colder. No fridge, I know this is how they are but why?! No food available after hours and the bar very much shut after midnight although 1am promised. Charges to use the safe, charges for wifi(getting more and more common in so many now though), vending machines of pop and crisps and no humans working... It's the easy jet of "hotels". Breakfast is some kind of hectic hell. All the food we had was cold. Mushrooms chewy and tasteless. So the "hot and tasty" heading seems to be a misnomer. Second worst hotel breakfast I have ever had. And then the queue for the lifts! Of the 3 lifts, one did not work at all whilst I was there. I heard a man ask the only person I saw in the main entrance where the stairs were and she gave him some health and safety speech but didn't tell him where they were. If I hadn't bumped into an old friend at that moment I would have pushed the point myself. The only good point I can think of was that the bed was comfortable.

We stayed here in February 2012. We then had to be as close to both Waterloo Station and the Royal Festival Hall as possible. It was an obvious choice for this February's visit for an RFH concert, even though the proximity criterion no longer applied. We knew what to expect and got it - comfortable beds, good breakfast, attentive staff. It was appreciably more expensive than before and clearly not included within the £29 per room offer. But the prime location is probably the reason, and we did not consider any alternative hotel.

Excellent service from the team.
Very convenient location.
Very quiet room, we are light sleepers but heard no noise in the nights.
Breakfast selection was good , but hot food was not really hot and on cold plates.
In-room heating was excellent.
