One of a number of properties in the UK which only seem to do harm to the Hilton brand.
If you take a look on trip advisor the general view seems to be it is acceptable for one night, but ought to be Travelodge above the door not Hilton, and likewise a price to match.
I very nearly stayed here last year but avoided it after some reviews I saw (maybe botb on here as well as trip advisor?!). There are a number of places like this in the UK which have a bad reputation, and yet, I stay now and again at the Warwick/ Stratford property which looks a similar set up and yet I always have a good experience.
