I stayed at the metropol for a week last winter. There is one five star hotel in Arosa but I wasn't interested in bringing food or schlepping back and forth for every meal. I did take the nicest room they had available at the metropol it had a balcony with a great view that I'll attach to this post. The room was recently redone but still super Yeshivish eg, no TV I had a negel vasser and krias shema al hamita next to my bed.
The skiing was insane though, best I've ever had I think it's 3rd biggest in Switzerland I took a mountain guide and highly recommend it he took me to all the peaks and all the great off piste spots that would have been very difficult on my own.
