I went there with my fiance (at the time), and we had an amazing time overall.
When we first arrived, we weren't sure what to make of it as we got lost within the facilities whilst trying to find the actual Spa. It seemed to be a bit of a maze getting there from reception but once we got there everything went smoothly. The venue itself was lush and top quality. The lightl was right, the facilities were perfect and the staff were really nice.
We had bought a spa day with light lunch and we we arrived, we practically had the pool to ourselves at times and the steam rooms only had a couple of other people in. Occasionally it felt like we had the place to ourselves which was great.
The treatments were unfortunately in separate rooms, but none-the-less, were at high standards.
The only negative was that the choice of 'light lunch' was very limited and we ended up paying in addition for a 'real' lunch. But aside from that, I would definately recommend this place and would go again! Especially if there were more offers as it can be a little pricey - but is worth the treat.
