I stayed at Clumber Park for three nights as a single business traveller.
The hotel has average amenities and is generally tidy, though the furniture and décor feel basic and dated. The bedroom carpet was heavily stained, although the room itself was clean and had everything I needed for my stay - it was essentially just a base for a few days.
I didn’t use the spa facilities, so I can’t comment on this aspect.
Food in the lounge was average.
I requested additional towels during my stay, but unfortunately they never arrived and there were only one set of pillow cases on the pillows on the bed.
On a positive note, the staff were polite and friendly, and the location is excellent with convenient parking.
