A bit late, but might be of use to others....
Functional but highly underwhelming would probably be a fair assessment.
I suspect the property was built in the 1970's. Very small rooms, badly ventilated, pleasant enough staff but on balance you may be better off staying at the Travel Inn next door. Rooms will be bigger and this probably explains the aggressive pricing at this place (£56 a night for this weekend).
There was a small pool, restaurant was fine, bar area was full of smokers.
Also, it's pushing it a bit to say this hotel is near Derby IMO
