I've now stayed here twice, and both stays pretty much the same. The rooms are comfortable, the service is excellent and polite. The amenities are good for gold card holders, but the Exec Lounge would benefit from some more choice on snacks. Location excellent - very close to Tower Hill tube.
My one gripe is that the Apple TV in the room appears to have no remote on/off switch so you need to get out of bed to switch it off. And it came on at 4:00am on its own accord to wake me up, which was annoying.
But otherwise rooms and perfectly adequate, nice shower.
