We ate dinner, slept, had breakfast, and hiked from Gstaaderhof hotel. All were a pleasure. Staff at desk and in restaurant are all impressively multilingual and extraordinarily helpful with good cheer. Food was excellent. Their menu easily accommodated our dietary restrictions. Excellent vegetarian and local pastured choices. We booked a small double room but it was more than sufficient for our needs and impeccably clean. Simply stroll to Gstaad pedestrian zone. The hotel desk staff were all experienced hikers who knew the trails and gave excellent advice for a route. The Gstaad official tourist info office, a 2-minute walk in the "town" center, was also helpful. It's right near a bus stop to the mountain top trail and that worked out great.
Only improvement would be having a lighter sheet for sleeping instead of only a down quilt. But this is all over Switzerland. I don't understand why they figure out to not wear winter coats in summer but still think you need a down quilt.
Biggest wonderful plus was the following. We planned to hike the day after we slept there then take the train after dinner and not stay at the hotel again. Knowing this, the staff OFFERED to hold our luggage at the desk while we hiked and suggested we use their spa showers upon our return! Which we did at no fee except our own freely offered tip. The underground spa was a trip unto itself! We would return here for sure.
