I stayed there with ten friends last January for the second time in a row and for the third time in Serfaus. Serfaus is the perfect ski holiday. Fine accomodations, perfect ski services and good apres ski and restaurants.
We stayed in two appartments and these are oke. The beds are a little bit short for larger people but everything is neat and clean. Breakfast is oke. No special things just the regular stuff. The pool is small but refreshing in the morning.
The hotel is nearby the metro that brings you to the ski center and if you want to walk it takes you about 10 minutes. You may not use your car during your stay!!!
Use the ski services as well!! Leave your skies and shoes at the center at the end of the day. It will cost you a couple of euros extra but you don't have tot carry all your stuff in the morning and in the afternoon.
