We stayed two nights between Christmas and New Years. The hotel provides pickup from the train station. We were impressed with the service, we were served hot wine upon arrival. The rooms are spacious and the jacuzzi tub is fabulous! The breakfast was exceptional. In addition to the buffet, you can also place a special order (we ordered pancakes). We ate two meal at the lobby bar, the service was good, but a bit slow, however, they allowed us to make a special vegetarian order, which is often difficult at best in C.R.
Our only complaint was that the spa. Expect to pay 44 Euro to use the sauna for 2 hours (by reservation) the pool will cost you 10Eur. The masages were more reasonably priced, and I was satified with mine. Be aware that the staff in the wellness center speaks German and Czech, but quite limited English, and my friend found that they lacked the profesionalisim that we expected from a five star hotel.
Overall we enjoyed our stay and would reccomend it if you plan to spend the majority of your time your time sightseeing, eating, skiing(in winter), golfing, playing tennis (in summer) and walking in town, but I could only cautiously reccomdend it if your sole purpose is to use the spa facilities.
