I stayed at the quaint, comfortable, well-situated Crusch Alva Hotel in Zuoz in February '12. The inn has a great location right in the middle of the small town, 2 minutes on foot from the train station, from where you can reach all the amazing ski resorts of the Upper Engadine in minutes by train, e.g. St. Moritz/Corviglia, Corvatsch, Diavolezza/Lagalp, Pontresina, Celerina, etc. Everything is within a short 10-20 minute train ride.
The hotel is small and intimate with a bright, cozy breakfast room, a good selection of breakfast items (breads, cold cuts, cheeses, cereal, muesli, juices, coffee, tea, etc.) and everything is nicely set-up, fresh and tastes great!
The rooms are very spacious for this hotel category with a seating area, super comfortable beds (loved the clean and fresh down duvets) and nice, large bathrooms.
Understand that Zouz is a small, quiet village, great for families with small children, but less suited if you're looking for night clubs and bars. (There are no night clubs, but a couple of cozy bars in town). The ski school in Zuoz is famous and extremely well-run. Zuoz is a great base if you're looking to cross-country ski or skate.
I will definitely return to Crusch Alva!
