Good - absolutely beautiful location, stunning in fact, inside and outside of the spa is excellent - wide selection of treatments (however, not so good if booked less than 3 days in advance) - great facilities, 25m indoor pool, Jacuzzi, Orangery, waterbeds for lounging, steam and sauna's, outdoor whirlpool, etc - lots for exercise: gym, country walks, 20 classes a day for a wide range of activities - rooms are great, bed is on the hard side but very comfortable, good selection of towels, toiletries, dressing table with mirror and outlets nearby, proper hair drier (I had a room facing the lake on the ground floor with doors opening to a set of chairs and table) - friendly staff, helpful (only met two that weren't so good...) - particularly liked the ballet/pilates type class (has fun instructor) - large facilities, even with a lots of people doesn't feel crowded (at least not overly so)Bad- website booking ahead of time for treatments is time consuming and badly designed - you have to select each treatment and be shown a range of times (I found most returned unavailable), so you end up having to select many treatments before you find anything available. I was booking two-three days in advance of my stay. Took me two hours to find and book treatments due to unavailability. And didn't get ones I wanted. When I arrived at the spa, the list of treatments printed for me was wrong, it didn't include treatments I booked with the room booking. quickly sorted though. For a spa, the treatment booking online and in-house should be slick, not cumbersome and time-consuming and error prone.- one staff member, on the gym class booking fitness desk was consistently blunt to the point of being rude (she 'barked' at me, then I noticed she was same to other people). Another, when asked a question, just said, "I'm new, I don't know" ... to a simple question like where is the spa treatment desk?- you have to book lunch and dinner each day. And when you arrive at the restaurant area, quite often, there is no one there to seat you. So you wait, and wait, and a cue forms.- one of my treatments, a 25 min one, started just over 10 mins late and then she quite obviously rushed and rushed and then finished early! so the treatment was really only for 19mins (24% less time) Something about the scrub mixture being the wrong one. Couldn't help feeling cheated. UglyFound 3 double charged items on my bill at check-out, she had to use a calculator and then manually do the sums on paper while I waited. 'charity and gratuity fee' is automatically opted in. Found two charges on my credit card for £1 from check-in... lots of errors.Overall, I really enjoyed my stay, and I can tell they work hard to keep people happy, I would go back again. They get the majority of things right, but if you come to de-stress, any issues ruin that goal. One unfriendly staff member, lots of overcharges, time-consuming online treatment booking, all detracted unnecessarily from my stay. The overcharging on the bill and the treatment booking online needs to be smarten-up. New online booking system and accounting system perhaps. And staff should be trained on the basics like where stuff is before they are front-of-house. Staff missing from key stations, like the restaurant desk, check-in desk, should not ever be the case.
