We had a great wintersport weekend here. Willingen is very close and Winterberg is a half hour drive. Rooms were great and spacious! Wellness facilities are amazing, Sauna, swimmingpool, steamcabin, bubble bath and so on. Breakfast is great, many choices and very german. The diner is ok but not of high quality!
If you want to book the hotel you can also check their own website for possible cheaper options!
