I had a wonderfully relaxing experience at this hotel, which seemed to combine both tranquil surroundings and luxurious amenities. The grounds were stunning, and the dining options were impressive. While the staff went above and beyond to ensure we were comfortable, I did encounter a couple of minor issues with the room's temperature and condition. Nonetheless, it was a fantastic escape overall.

I had a truly lovely experience at this hotel, enjoying clean and spacious rooms that felt modern and comfortable. The staff went above and beyond with their helpfulness and charming manner. However, I found the signage to be quite misleading, making it challenging to locate the hotel. The dining experience was fantastic, especially the freshly cooked meals, but the option of relaxing in the beautiful grounds was limited due to weather concerns during my stay.

I booked a spa day for my wife and her mum, and though the staff were welcoming, the lack of a working jacuzzi was a letdown. The food presentation was nice, but the quality didn't meet expectations. Overall, the amenities felt outdated, especially compared to other venues I’ve experienced. It wasn't the luxurious escape we were hoping for.

The spa facilities were decent, but the experience felt limited without the jacuzzi, which would have been a major highlight.

I had such a delightful time at the hotel! The staff were incredibly accommodating, and I enjoyed the lovely breakfast. The spa facilities were a great addition to my stay, really allowing me to unwind. However, a little refurbishment would elevate the overall experience, as some areas felt slightly dated. Overall, great value for a relaxing getaway.

Overall, the hotel has a beautiful setting surrounded by well-kept grounds, perfect for a relaxing getaway. The service experience was pleasant, with staff being friendly and attentive. Unfortunately, the dining experience could use significant improvements, especially with the afternoon tea offerings which fell short of expectations. The spa facilities were outstanding, providing a refreshing break, making the stay enjoyable despite some areas needing attention.
