"Nice but too far from town"

8.0

Hotel is spotless, staff very friendly. Leisure centre is great.

Asked for an iced latte at breakfast and rather than charge the room, there was a huge deal made where my husband had to go to the room for his wallet to pay for iced latte. Totally over the top.

"Charlotte was great!"

My sisters and I visited the spa over the weekend. My masseuse, Charlotte, was wonderful and very professional. She was very friendly and informative and gave me recommendations for my skin type. The massage was lovely.

"Truly Maguc Treatment with Eva.."

10.0

Went to the Spa, not my first time here. Always a lovely experience but had to post after today's treatment as it was truly fabulous. I had the hot stone massage with Eva. It was hands down the best massage I have had. Eva's technique was sublime she is Amazing... I will be back not just for the this particular treatment but to Eva. So relaxed I did not want to leave. Thank You Eva! ๐Ÿ˜Š

"Not good enough service"

6.0

Hotel is gorgeous and so is food,only problem was the service.We were in the lounge area and were waiting to order a drink,the young lady asked everyone if they were okay except us and done this repeatedly even when we were clearly trying to order a drink.Really let the hotel experience down but overall it was lovely.
