"Nice rooms but I'll try somewhere else next time"

6.0

Rooms are large, beds are huge and comfortable. Staff are lovely

1. the car park lights are on all night and shine straight into all the bedrooms at the front of the hotel. If you are on the second floor the windows are curved at the top and let all the light in. Its better on the first floor but not good enough, Just turn the lights off after midnight. 2. The gym is open to the public and feels like a public leisure centre rather than the spa experience it looks like in the pictures - really busy - couldn't get on a treadmill in the middle of the day. Swimming lessons in the pool. no room in the hot tub... considering the price of the hotel room I would have expected an exclusive gym - or at least to be able to use it.

Good location and nice setting. Friendly staff

Needs a bit of a refresh. Little maintenance needed. I do not thing it's price is justified for the hotel.

Always pleasent, always relaxing, always quality, alas becoming too expensive for me and my family and friends. Most of the amenities are beyond my purse. I have been a customer now for at least 20 years but now Im a pensioner it has to stop. Regards Maurice Daly

"Great stay - will consider again"

9.0

Very comfy bed, friendly staff, good food and excellent breakfast

Having the sugar cubes individually packed is not very ecological, even if I am aware that this is a hygiene decison. Creates a lot of plastic waste though.
