We spent five or so nights here last February, and I'd say this is probably the best hotel in Arosa (the other option is the Kulm). The architecture is quite interesting, since there is a significant contrast between the rustic main hotel, and the ultra-modern HUGE spa. The rooms are quite spacious, very well appointed, and all seemingly quite new. The bathrooms are awesome, with overhead rain showers, and they are all covered in the same granite they used in the spa. The views from the private balconies are great overlooking the mountain, especially at night.
There are three restaurants in the hotel: large formal dining room, a more intimate upscale restaurant directly adjacent, and a more rustic, classically Swiss restaurant downstairs, complete with kegelbahn. All three restaurants are great.
If you're in Arosa during the winter, you're probably there to ski. There is a ski shop on site with everything you need. I normally travel with my own skis, but I didn't want to schlep them all the way to Europe, and I'm glad I didn't. Tschuggen is pretty much ski-in, ski-out, and there is a really awesome monorail that takes guests directly from the hotel to the mountain. This was seriously one of the coolest monorails I've ever been in.
The spa is one of the best I've ever seen; if not, then it was certainly the largest. The pool area is massive. The dry sauna is also quite large, and really well done in logs of wood. Every day during our stay there are special Aufguss sessions, which were always nice.
I'd been skiing in Switzerland twice prior, once in Davos and the other time in St. Moritz. Arosa was my favorite, thanks in large part to the Tschuggen.
