We were only there for one night, thankfully. The main problem was the bed, which was far too hard. We were unable to get to sleep, and next day we were aching from the hard matress. Judging by other reviews I've seen, I'm guessing that they've just had new beds installed, and I have to say that other Premier Inns I've stayed at haven't had this problem. The pillows were also uncomfortable, as though they were quite well used, and had gone flat. One pillow wasn't high enough, add another and you were too high.
Added to this, there is a busy road, then a main railway station, then the motorway running parallel to the hotel in that order. There is no air conditioning in the hotel rooms, and they only provide a little fan, so it's my guess that in warmer weather you wouldn't sleep a wink. We were very disappointed indeed, and mentioned it to the receptionist the next morning. However, the "goodnight guarantee" apparently is not actually applicable to a night without sleep . . .
