A warm, welcoming hotel! We have just spent the Christmas week here (on half-board), and it was great! The usual excellent 5-course dinner became an excellent festive 6-course dinner on Christmas Eve and Christmas Day. The breakfast buffet was also extensive. All the hotel staff were very helpful.
Although the hotel is not near the ski lifts, they run a regular shuttle right up to the Lift Station in the morning, and a regular shuttle back from the Lift Station in the afternoon. So, although some guide books advise against staying in Flims Waldhaus because it is a good way (more than half a mile) from the Lift Station, it was very easy getting to and from the slopes - much easier than staying in Flims itself and walking up to the Lift Station (which we have done on a previous holiday). The hotel will also pick you up from the Bus Stop if you are travelling by train/Postbus to get to the resort.
Their spa facilities are excellent too, with a fantastic outdoor pool with various massage jets - great for massaging post-skiing aching limbs!
All in all, a very enjoyable stay!
