Not the greatest experience at all. We had a "Premium Room" from 25 Dec - 30 Dec 2018. It was awful and smelt like a wet dog.
The passageway outside the room was worse and must have had some kind of damp problem, with a smell so terrible sometimes - we gagged walking to our door.
The exit at the end of the passage seemingly was boarded up with bits of cardboard etc and just looked tacky.
In all, the damp and generally what felt like uncleanness lead to feeling ill the whole stay and needing to take medication for allergies (in London, in winter).
