The common areas (lobby, restaurants, etc.) are quite nice: four stars. The rooms, however, are pretty basic: 3 stars at best. But it's a pricy town and the rooms are reasonable. The sledding center and Bob Sled tracks are nearby, a big plus in the winter time. Easy downhill walk to the lake. We ate at the restaurant twice and were very pleased with our meals. Tour groups occupy the large dining room and can get quite loud. But we were happy to have some privacy in the smaller dining room.
Our quarter-circle shower had a major leak due to torn gaskets in the doors. Should have been addressed long ago.
A big plus is the local travel card. We rode buses, furniculars and ski lifts for free during our August stay. That alone saved us more than 160 CHF in just one day.
